Probably the biggest match of the weekend with both sides knowing a win will be enough to take them through. Leicester will top the pool if they get a bonus point win while they'll secure a best runner-up spot if Clermont manage to get the bp win away to Viadana. The Ospreys know that a win will also be enough to see them get through as a best runner-up, their chances of topping the pool are slim as they need Viadana to cause an upset against Clermont. As for the match itself it's also the hardest to call of the weekend, with their home form you'd expect the Ospreys to take it but if there's any side that can go away from home in the final round to pick up a win to get through it's Leicester and their recent form is none too shabby either. Should be a tense occasion in Swansea.
