Investec Champions Cup Round 4: All you need to know

As we turn towards the final round of pool games in the Champions Cup, the stakes are different for all four Irish provinces.

With three wins from three so far, Leinster's place in the last-16 is secure, but Leo Cullen's side know a win away to the Leicester Tigers will give them home advantage in the next round, as well as the quarter-final should they get there.

Munster are in a sort of holding pattern for their meeting with the Northampton Saints; Graham Rowntree's side are all-but-certain to be in the Round of 16, but a home draw is more than likely out of reach. As such, the URC champions are playing for seeding on Saturday evening.

Ulster are backed into a corner after their defeat to Toulouse. Probable results elsewhere mean that Dan McFarland's side will almost certainly need to beat Harlequins to qualify for the knockout stages.

Connacht kick the weekend off against Bristol on Friday night. While the province can technically still qualify for the next round, it would take some unlikely results elsewhere, although a win should be enough for fifth place in the pool, which would get them into the Challenge Cup knockout stages.
