Leinster annihilated Gloucester in a nine try display, keeping their 100% win rate in the Heineken Cup alive in a battering at the RDS tonight.

James Lowe started the scoring spree in the thirteenth minute. Caelan Doris nicked the ball at the ruck and freed the winger who sored past Billy Twelvetrees finishing into the corner, electrically. 

Josh van der Flier then scored his third European try in two matches, Ross Byrne landing his first conversion for 12-0. 

From a maul, hooker Ronan Kelleher increased the lead to 17-0 before his opposite number, Henry Walker, was sin binned. 

Leinster took full advantage with tries from Kelleher and James Ryan, both converted by Byrne, sending them into the interval 31-0 ahead and bonus point in the bag. 

Scrum half Luke McGrath got in on the scoring fun early in the second half. Lowe then grabbed his second try of the night after being freed by a nifty second assist from Doris. 

Substitute Jordan Larmour put decorated Leinster's cake with icing when he scored on his return from injury. 

Doris bulldozed over for a deserved try late on with Johnny Sexton's conversion the last act of the match. 

Leinster looking at home in the Heineken Champions Cup.
