James Haskell is not afraid to say what he thinks. This time he is told to pipe down when he is penalised by Nigel Owens and questions the decision.

Not what anyone of a Leinster allegiance wants to see. Johnny Sexton appears to have a shoulder injury after being crunched by James Haskell.

Wasps would be pleased to see him disappear down the tunnel. He's made of stern stuff though. He's fine.

Leinster let Wasps off the hook. Richardt Strauss and Tadhg Furlong lead the Leinster charge in to the visiting 22 before Isa Nacewa kicks through.

Belting it down with rain in Dublin. Whether the greasy ball contributes to a truly awful passage of play from Wasps I'm not sure. Maybe it does, if we're being generous. 

Danny Ciprani tries to play his way out of bother, sending a hospital pass to Jimmy Gopperth, who tries to rectify the situation by shovelling the ball over to Christian Wade. He finds touch...

Johnny Sexton has his green gumshield in his left hand, white ball in the other. The Leinster fly-half gets us moving again.

The Wasps players are the first to re-emerge from the Aviva tunnel. They're all looking a bit sheepish. Presumably after getting a half-time rollicking.

Willie le Roux may have had a shocker but that first half was covered in blue. Wasps are playing far too loose and their England players look unrecognisable. 

Sean O'Brien putting in a serious and timely shift ahead of Lions announcement on 18 April. Andy Farrell, watching beneath us, must have taken note.

I'd love to see what's going on in the Wasps changing room right now. I reckon Dai Young has told Willie le Roux to stand in the naughty corner.

When Willie le Roux crossed but did not touch down it was against the run of play. Kurtley Beale went right through the middle and left three Leinster defenders floundering.

We had looked away. It was only when we saw the replay then we realised what he had done. It was an anomaly.

Small Man Peaky: Wasps getting absolutely pumped here. No way they're coming back from this. le Roux is not going to be popular in Cov  

John McEnerney:  Plenty of match winners on both sides but the Lansdowne Road Roar will be what wins it for the home win just like The Slambusters

I'm very surprised at the gap between the two teams. Wasps came here with a lot of confidence but some of their players have been anonymous. There is a lack of cohesion.

Leinster brilliant, Wasps woeful. The away team have not recovered from that Willie le Roux mistake at 8-0.

Leinster are dictating everything. The home fans can nip downstairs for a pint without worrying about missing much. Half-time almost upon us.

Can Wasps haul themselves back into this before the break? I wouldn't bet on it. They briefly threaten through Kurtley Beale, but Thomas Youngs' kick cannot be picked up by a team-mate and the chance goes begging.

No problem. Jimmy Gopperth - Wasps' kicking machine - slots over from distance. The visitors will be happy with this scoreline considering they have been well under the cosh.

Another chance for Wasps to get their side of the scoreboard creaking into action. The visitors win a penalty, and Jimmy Gopperth is going for the sticks.

Boy, are Wasps pleased to hear Nigel Owens' whistle go in their favour. Luke McGrath looks to be clean through with Richardt Strauss on his shoulder - but he is hauled back by the eagle-eyed referee who spotted an infringement.

Another Leinster penalty after a high tackle on Joey Carbery. Johnny Sexton kicks into touch about 10m outside of the Wasps' 22 - more questions are going to be asked of the Wasps backline.
