Champions Cup Round of 16 - All you need to know

The Six Nations is behind us, and we're officially into the business end of the season.

For the 16 remaining teams left in the Heineken Champions Cup, the road to the Aviva Stadium and the final on 20 May is starting to straighten out, with just four wins separating those left from getting their hands on the trophy.

Of the 16 teams remaining three are Irish, but there will be two at most still standing next week, with Leinster hosting Ulster at the Aviva in an Irish derby on Saturday evening.

As top seeds, Leinster will be on home soil for the rest of the competition, even the final should they get there. Whether they play one or four games between now and the end of May is still to be decided.

Ulster will be out to cause a big upset against their neighbours, but will have to park some bad memories of their last visit to Dublin in December, throwing away a 19-point lead against Leinster at the RDS before eventually going down 38-29.

And while that derby provides Leinster and Ulster with a familiar task, the same can't be said for Munster, who have traveled to Durban for the first time to face the Sharks, battling both the scorching weather conditions as well as a team loaded with Springboks, as they look to reach a record 20th quarter-final.
