The big game in Pool Four this weekend pits French side Bayonne against Sale Sharks in a clash that could decide the group winners, while Petrarca Padova entertain Montpellier. We preview all the action!
Bayonne v Sale Sharks, Stade Jean Dauger, Saturday 8 December, 19:45 GMT
Sale head to France for their crucial European Challenge Cup game against Bayonne without the services of Luke McAlister and Lee Thomas. McAlister is suffering from a groin problem whilst Thomas has a knock to his knee.
On top of that Ben Foden is away on England Sevens duty, although Juan Martin Fernandez Lobbe is fit again and will play some part from the bench.
"This will be a tough game for us as Bayonne are a very good team on their own ground," said Sale director of rugby Philippe Saint Andre.
"We want to win the group and this is a game we must win. Luke McAlister has been struggling with a groin injury this week and we have decided to rest him and get him fit for the return game next week.
"I am pleased that Juan Martin Fernandez Lobbe is fit again and he will play a part in some of the game on Saturday."
Bayonne include two French caps in their back line, Richard Dourthe at full-back and Xavier Garbajosa at outside centre. Australian A fly-half Manny Edmonds will direct proceedings in the number ten jersey.
