Leinster will aim to secure a top seeding for the semi-finals when they take on Lyon this weekend.
Leo Cullen's side have already secured qualification for the knock-out stages after winning their first four matches in Pool 1 with three bonus points.
Unbeaten in the PRO14 and dominant 54-7 winners over Connacht last weekend, the rampant Blues' focus now switches to Lyon.
