The second round of back-to-back European games takes place this weekend with some thrilling encounters across the continent. The Irish trio of Munster, Ulster and Leinster will look to complete the double over English opposition, while Glasgow Warriors are aiming to do the same against La Rochelle. Elsewhere Benetton and Connacht will try to bounce back on home soil and the Ospreys face the unenviable task of trying to win away at Racing 92. FRIDAY Harlequins v Ulster 19:45, The Stoop Ulster will look to make it four wins from four in south west London on Friday evening as they travel to take on Harlequins. It took an almighty fightback for Dan McFarland’s team to win the home game, sneaking through 25-24 in their second one-point win in three matches. With free-scoring Clermont just a point behind them in the pool, and a trip to the Massif Central still to come, this game is huge for Ulster’s quarter-final hopes. They will take plenty of heart from their recent record against Quins, with four wins in a row against the Premiership side, while in Marcell Coetzee they have the second highest carrier of the competition (only CJ Stander has made more). If they can add a second win in England this season, Ulster will be in prime position to return to the quarter-finals for the second year running.
