Leinster play Saturday, Munster on Sunday

Leinster are the first of the Irish provinces up in this month's European Champions Cup semi-finals.

The Blues' clash with Welsh outfit Scarlets is to be played at the Aviva Stadium on Saturday April 21 and will kick-off at 3:30pm.

The Landsdowne Road venue has seen some great Leinster victories over the years but has also been a happy hunting ground for the Welsh club who hammered Munster there last year in the PRO14 final.

The Stade Chaban-Delmas in Bordeaux will host the meeting of Top 14 side Racing 92 and Munster in the second semi-final.

That will take place on Sunday April 22 with kick-off at 3:15pm Irish time.

The two Irish provinces will be hoping for victories to set up just the second ever all-Irish final, in Bilbao, and the first since Leinster defeated Ulster at Twickenham in 2012.
