Leinster have beaten Bath 18-15 to reach the semi-finals of the Champions Cup.

Matt O'Connor's men survived a nerve-jangling last few minutes to prevail at the Aviva Stadium, having led 15-5 at half-time.

Ian Madigan stepped up to the plate with an excellent performance, kicking six penalties over 80 highly competitive minutes.

George Ford and Stuart Hooper bagged the Bath tries, the second of which was converted by Ford.

Leinster will travel to the winner of Toulon and Wasps in the last-4.

Today's other quarter final sees Clermont play host to Northampton (5.45).
