European club rugby returns from 16–18 October as 18 teams from eight nations begin their campaigns in the EPCR Challenge Cup, with the final at Lyon's OL Stadium on 21 May 2027 the ultimate prize. The opening weekend brings together former European champions, ambitious emerging clubs and established contenders hoping to take their first steps towards silverware. Edinburgh 
face a Toulon side they have never lost to, the Sharks return to the ground where Lyon ended their European hopes in 2025, and last season's runners-up Ulster begin another campaign away to Zebre Parma. Elsewhere, Harlequins will be looking to use their European experience to their advantage against Vannes, while Georgia's Black Lion have an opportunity to make a statement on home soil against Ospreys.
There are also significant changes to the competition that could affect how teams approach their opening fixtures. The top three clubs in each of the three pools will qualify automatically for the Round of 16, with the three remaining Challenge Cup qualification places awarded to the clubs with the highest match-points totals across all pools. Four additional teams will enter the knockout stages from the Investec Champions Cup. The attacking bonus-point system has also changed, with teams now required to score at least three more tries than their opponents to earn the additional point. With only four pool matches per club, the opportunities to recover from a poor result are limited, and every point could make the difference when qualification is decided in January.
Dragons begin their European campaign with an opportunity to settle an old score against Perpignan, a side that has historically enjoyed the better of this fixture. According to Oval Insights, USAP have won six of the eight previous meetings between the clubs, giving them a 75% winning record overall. However, the picture changes considerably when the fixture takes place at Rodney Parade, where Dragons have won two of their three previous encounters against the French side. With the Welsh outfit having reached the semi-finals of last season's competition, there will be an expectation that they can carry some of that European form into a new campaign. The challenge will be maintaining their physical intensity and territorial control against opponents who have demonstrated an ability to make significant ground with ball in hand.
The tactical battle could be particularly interesting given the different strengths of the two sides. Dragons led last season's Challenge Cup for kicks in play with 205, accumulating 6,566 kicking metres, while also recording the highest number of scrums won in the competition. Thomas Young was another standout performer, winning nine turnovers, the joint-highest total in the tournament. Perpignan, meanwhile, finished second for metres per carry, with Peceli Yato providing a particularly effective option through contact. If Dragons can use their kicking game to force USAP into difficult areas of the pitch while maintaining control at the breakdown, they will give themselves a strong opportunity to begin with a victory. However, allowing the French side to generate quick possession and build momentum through their powerful ball carriers could quickly change the balance of the contest.
ATR verdict: Dragons have a genuine opportunity to win at home, but their kicking accuracy and breakdown discipline will need to be excellent against opponents with the stronger historical record.
One of the standout fixtures of the opening weekend sees Edinburgh welcome former champions Toulon to the Scottish capital in a matchup that has consistently favoured the hosts. Edinburgh have won all three previous meetings between the clubs, scoring 101 points and conceding just 51, including a memorable bonus-point victory in last season's Champions Cup. Their domestic performances have provided further encouragement ahead of the new European campaign, with consecutive victories over Zebre Parma, the Stormers and Ulster establishing an impressive early-season winning run. Magnus Bradbury has been central to that momentum, leading the URC with 55 carries, while Edinburgh's 471 team carries demonstrate a clear willingness to maintain possession, build phases and challenge opponents through sustained attacking pressure.
Toulon arrive with a different set of strengths and will be determined to reverse a European head-to-head record that makes uncomfortable reading. Although the French side have lost three of their previous five fixtures, they returned to winning ways against Racing 92 and continue to boast impressive statistics around the set-piece and defensive contact. Their scrum success rate of 92.5% ranks among the best in the TOP 14, while their defensive organisation and ability to win tackle turnovers provide the foundations for a more controlled approach. Edinburgh will need to prevent Toulon from dictating the pace through their forwards, particularly if the match becomes a territorial battle dominated by set-piece exchanges. The Scottish side have demonstrated that they can stretch opposition defences through their carrying game, but sustaining that intensity against one of France's most physical clubs will be a considerably different challenge.
ATR verdict: Edinburgh have the form and historical advantage to make it four victories from four meetings, although Toulon's forward power could make this a much tighter contest than previous encounters suggest.
Lyon and the Sharks renew a rivalry that produced one of the significant results of the 2024/25 Challenge Cup knockout stages, when the French side secured a 34–21 victory to eliminate their South African opponents in the Round of 16. The Sharks return to Matmut Stadium determined to reverse that result, having demonstrated encouraging form during the opening stages of their URC campaign. Victories over Leinster and Ospreys have contributed to three wins from their previous five fixtures, providing some momentum ahead of their first European assignment. Lyon, however, will have added motivation of their own, with the 2027 Challenge Cup final taking place in their home city. The possibility of competing for silverware in Lyon provides an obvious incentive, and a strong start against one of South Africa's leading clubs would help establish their ambitions.
The previous meeting provides an indication of the tactical challenges awaiting both teams. Lyon controlled important areas of the contest through their forward pack and were particularly effective at the set-piece, having completed last season's Challenge Cup campaign without losing a scrum. Their ability to maintain possession and dictate territory remains an important part of their approach, while their attacking options allow them to exploit opportunities created by sustained pressure. The Sharks will look to counter that control with their own physicality and defensive organisation, having recorded an 83.2% tackle success rate in last season's competition. Tinotenda Mavesere was a standout performer during the previous encounter, making 118 metres, beating nine defenders and completing 14 tackles despite the defeat. If the visitors can establish a more effective attacking platform than they managed in 2025, they have the personnel to challenge Lyon throughout.
ATR verdict: One of the hardest fixtures of the weekend to predict. The Sharks have the quality to reverse the previous result, but Lyon's home advantage and set-piece consistency could prove decisive.
Black Lion welcome Ospreys to Tbilisi for the first meeting between the clubs in EPCR competition, providing the Georgian side with an opportunity to test themselves against established Welsh opposition. Their participation in the Challenge Cup has provided valuable exposure to a higher standard of club rugby, particularly for players who form part of Georgia's wider international pathway. Black Lion have developed a reputation for physical performances, especially around the scrum and breakdown, and will view home fixtures as important opportunities to establish their competitiveness. Oval Insights statistics show that they earned penalties from 20% of their scrums during last season's competition, a higher proportion than any other participating club. Giorgi Sinauridze also played an influential role, leading the squad with 43 carries and five turnovers won.
Ospreys arrive with a powerful forward platform of their own and have already demonstrated the effectiveness of their driving maul during the opening weeks of the URC. Six maul tries in three matches underline the quality of their set-piece execution, while their 23 turnovers won place them among the leading teams for breakdown effectiveness. Sam Parry has been particularly productive close to the try line, and the Welsh side will look to use their experience and organisation to control possession inside the opposition 22. Black Lion's ability to challenge at scrum time could disrupt that approach, creating an intriguing battle between two teams with clear strengths in the physical exchanges. Ospreys may possess greater European experience and attacking depth, but facing a motivated Georgian outfit in Tbilisi is unlikely to provide a straightforward opening assignment.
ATR verdict: Ospreys have the attacking quality to take the points, although Black Lion's set-piece strength and home advantage could keep the result in doubt.
Ulster return to the Challenge Cup following their defeat in last season's final, beginning their new campaign with a familiar URC encounter against Zebre Parma. The Irish province have historically dominated this fixture in Italy, with Zebre recording only two victories in ten previous home meetings, although the domestic form of both teams suggests this encounter could be less predictable than the record indicates. Neither club has won in its previous five fixtures, with Ulster recording draws in their most recent two outings, leaving both sides searching for a result that could provide renewed confidence. For Ulster, the return to European competition offers an opportunity to reconnect with the attacking performances that carried them to last season's final, while Zebre will be determined to improve on recent results and make home advantage count.
Ulster's attacking statistics from last season's Challenge Cup underline why they remain a dangerous opponent despite their domestic difficulties. They scored 265 points and 35 tries, ranking second in the competition for both measures, while Zac Ward recorded 423 metres and beat 31 defenders, the highest individual total in that category. Jacob Stockdale also contributed 376 metres, offering another significant threat out wide. Zebre, however, have the defensive tools to disrupt that attacking platform, having led last season's competition for turnovers won with 47. Their ability to contest possession around the breakdown and generate pressure through their maul could prove particularly important against an Ulster side that has struggled to turn promising performances into victories. If the Italian team can prevent Ulster from generating quick possession and force the visitors into a more fragmented contest, the opportunity for an upset becomes considerably greater.
ATR verdict: Ulster's attacking depth gives them the edge, but they will need more control than their recent domestic performances have demonstrated.
Scarlets welcome Newcastle Red Bulls to Parc y Scarlets in an Anglo-Welsh encounter that carries an additional storyline through the return of Stephen Jones. The former Scarlets player and coach is now part of Newcastle's coaching setup and will return to a ground where he enjoyed considerable success during his playing and coaching career. Both clubs have endured difficult starts to their domestic campaigns, recording just one victory in their previous five matches, making the opening European round an opportunity to generate momentum. The home side will take encouragement from a number of impressive individual performances despite their inconsistent results, particularly those of Blair Murray and Josh Macleod, who have been among the leading players in the URC during its opening rounds.
Murray leads the URC for running metres with 379 and has beaten 18 defenders, while Macleod has completed 57 successful tackles and demonstrated significant activity around the defensive breakdown. Their contributions highlight the balance Scarlets can offer between attacking creativity and defensive intensity when they are able to establish consistent possession. Newcastle possess dangerous attacking options of their own, with Christian Wade producing a remarkable performance in the club's most recent Premiership fixture, scoring three tries and making five clean breaks. The visitors also demonstrated impressive breakdown work in last season's Challenge Cup, ranking among the leading teams for jackal turnovers and lineout steals. Their ability to disrupt Scarlets' possession could be important, particularly if the Welsh side attempt to develop an expansive attacking approach. With both teams searching for greater consistency, the opening exchanges could have a considerable impact on confidence.
ATR verdict: Scarlets should benefit from home advantage, but Newcastle's counter-attacking ability and breakdown pressure make this a potentially difficult fixture.
Bayonne begin their Challenge Cup campaign in excellent domestic form, having recorded three consecutive TOP 14 victories ahead of their opening fixture against the Toyota Cheetahs. Their performances have demonstrated an effective balance between forward power, territorial pressure and accurate finishing, with the Stade Jean Dauger providing an imposing setting for visiting teams. The French side have already scored three driving-maul tries in the TOP 14 this season and rank among the competition's leading clubs for penalties won through their maul. Their kicking accuracy has been equally impressive, with the team converting 88.2% of their attempts at goal and Joris Segonds recording a remarkable 94.1% success rate. Those figures underline the importance of discipline for the Cheetahs, who could find themselves punished heavily if they repeatedly concede penalties in their own half.
The South African visitors will look to challenge Bayonne through a different approach, using quick possession and efficient breakdown work to prevent the hosts from controlling the tempo. The Cheetahs averaged a ruck speed of 3.6 seconds during last season's Challenge Cup, the fourth-fastest rate in the competition, while also maintaining an encouraging disciplinary record by conceding just eight penalties per 80 minutes. Their ability to generate quick ball could create opportunities against a French side that prefers to dictate territory and maintain physical pressure. However, the visitors will need to be effective at the set-piece and avoid allowing Bayonne repeated attacking opportunities close to their try line. If the hosts are able to dominate possession and turn their forward superiority into points, the task facing the Cheetahs could become increasingly difficult as the match progresses.
ATR verdict: Bayonne enter as favourites given their domestic momentum, home advantage and impressive set-piece performance.
Three-time Challenge Cup winners Harlequins return to European competition with a home fixture against RC Vannes, hoping to establish an early advantage in what looks to be a competitive Pool 3. The London club possess the attacking talent to trouble any opponent when they are able to move the ball quickly and create space, with Marcus Smith and Chandler Cunningham-South among the players capable of influencing their campaign if selected. Their opening Premiership performances have highlighted that attacking ambition, with Harlequins accumulating 1,535 carry metres and recording 28 initial breaks, ranking second in the league for both measures. Cunningham-South has been particularly influential through contact, leading the Premiership for post-contact metres with 65 and dominant contacts with 14, providing the kind of physical platform that allows the club's more creative players to attack against unsettled defences.
Vannes, however, arrive with several qualities that could make this a difficult encounter for the hosts. The French side lead the TOP 14 for defensive ruck entries with 391 and have demonstrated an ability to spend sustained periods in opposition territory, recording 111 possessions in the opposition half during the current domestic campaign. Their willingness to contest possession and slow attacking ball could prove especially important against a Harlequins side that is most dangerous when able to play at pace. Sione Kalamafoni has also been a productive defender, ranking among the leading players in France for successful tackles per 80 minutes. If Vannes can prevent Quins from generating quick possession and force them into a more structured territorial contest, the visitors have an opportunity to challenge. Harlequins will need to be disciplined at the breakdown while making the most of their opportunities to attack wider channels.
ATR verdict: Harlequins should begin with a victory, but Vannes possess the defensive organisation and physicality to make this a demanding opening fixture.
The opening round concludes in France as Castres Olympique welcome Benetton Rugby in a repeat of their 2025 Champions Cup Round of 16 encounter. Castres emerged victorious on that occasion and have historically enjoyed the better of the matchup, winning three of the five previous meetings between the sides. However, neither team arrives with convincing recent domestic form, with Castres recording just one victory in their previous five TOP 14 matches and Benetton entering the weekend without a win in their last five fixtures. Both clubs will therefore view European competition as an opportunity to reset their seasons and build confidence ahead of the next block of domestic fixtures. The home side will look to use the physicality and territorial pressure that have traditionally characterised their performances at Stade Pierre-Fabre.
Castres have demonstrated impressive defensive intensity despite their inconsistent results, with Baptiste Delaporte leading the TOP 14 for successful tackles this season with 84. Their attack has also shown an ability to generate momentum through contact, ranking third in the French league for post-contact metres and dominant carries. Benetton provide an interesting contrast, having led last season's Challenge Cup for try assists and initial breaks, statistics that highlight their ability to create opportunities through movement and distribution. Onisi Ratave was particularly dangerous during that campaign, averaging 10.4 metres per carry and accumulating 385 running metres. The visitors will need to maintain attacking accuracy while limiting the impact of Castres' physical forward pack, particularly around the breakdown. If they can generate quick ball and bring their most dangerous runners into the game, Benetton have the ability to challenge the hosts despite their difficult recent form.
ATR verdict: Castres have the historical advantage and home conditions in their favour, but Benetton possess enough attacking ability to produce a competitive finish to the opening weekend.
Pool 3 could quickly develop into one of the most competitive groups in the tournament, with Edinburgh, Toulon, Harlequins, Vannes, Ospreys and Black Lion all competing for qualification. Edinburgh's opening meeting with Toulon and Harlequins' encounter with Vannes could provide important early indications of how the pool will develop, particularly given the limited number of fixtures available to every club. The revised qualification system also increases the importance of bonus points, with teams competing not only against their direct pool opponents but potentially against clubs in other groups for the remaining knockout places.
Another major storyline will be the response of clubs entering European competition after difficult domestic results. Ulster, Newcastle, Scarlets, Castres and Benetton all have an opportunity to use the opening round to improve confidence and establish momentum. The Challenge Cup has repeatedly demonstrated that clubs struggling in domestic competitions can still produce impressive European performances, particularly when facing unfamiliar opponents or playing in different environments. With heavyweight clashes, first-time meetings and renewed rivalries across the three days, Round 1 offers an intriguing introduction to a competition that promises considerably more uncertainty under its revised format.
