With that brings plenty of scar tissue, but also an extra motivation to right the wrongs of the past. Leinster would have been circling this game since the start of the season, but they come up against a formidable outfit in Bordeaux. Bordeaux’s Louis Bielle-Biarrey celebrates. Photograph: James Crombie/Inpho The French side have the free-scoring Louis Bielle-Biarrey, arguably the best winger in the world, as well as a host of top French internationals like Yoram Moefana, Matthieu Jalibert and Damian Penaud. Leinster are 9/4 to win for a reason, but it is not beyond their capability if they perform in pressure moments.Ulster have an even more difficult task against Montpellier, who are second in France’s Top 14, and are 23/10 to win. The French side have a particularly strong pack, with young number eight Lenni Nouchi one to watch. Ulster have the extra motivation of needing to win to secure Champions Cup qualification for next season, having fallen out of the top eight of the URC on the final day.Who will referee the matches?Two English referees will take charge of the matches, Karl Dickson will referee Leinster against Bordeaux, while Matthew Carley will referee Montpellier against Ulster.
