Sunday's matches

Bristol v Leinster, Pool 4, 1345

Bristol, who need to win and score several tries, have recalled England wing Peter Christophers in place of Brendon Daniel, who has a broken thumb.

Leinster - who are four points ahead of their opponents, the only team that can catch them - have a close to full strength line-up and know that a win would guarantee them a home quarter-final draw.

London Irish v Toulouse, Pool 5, 1345

London Irish, already eliminated from the Pool Five equation, have only pride to play for against visitors Toulouse.

Despite the match's meaningless status, London Irish have named a strong side with Rob Hardwick, Kieron Dawson and Brendan Venter all starting through squad rotation.
