Garry Ringrose stars as Leinster rout Leicester at the Aviva

But for a five minute spell early in the second half, this Leinster win didn't look in much doubt.

Leo Cullen’s side marched on to another Heineken Champions Cup semi-final with a 31-point win against the Leicester Tigers, but despite scoring seven tries against the Premiership champions, there's a sense they'll need a more rounded 80 minutes in the last four, against either Toulouse or the Sharks.

With 45 minutes played in this contest, there was a fleeting moment when the 27,000 fans at the Aviva Stadium thought a shock may have been on the cards.

Three tries in nine minutes ended the contest, as Jamison Gibson-Park and Scott Penny crossed either side of a penalty try, while Jimmy O'Brien and John McKee completed the second half domination, as the favourites found another gear to breeze past a Tigers side that ran out of gas after 50 minutes.

Garry Ringrose lit up the Aviva Stadium as Leicester could barely lay a hand on him in the opening half as he ran in for two beautiful tries, the first coming after just 73 seconds of the game.

The glut of second-half tries gloss over what was a sloppy first 50 minutes from the hosts, who saw their breakdown badly disrupted by Leicester in then opening half, while a shoulder injury for Ryan Baird after just over 20 minutes
