Dallaglio now wants his side to seal fourth place in the Premiership

"Most people predicted an away win and it really irritated me and my friends in the dressing room," he said after the win at Adams Park.

"We have to be really pleased with that performance because of the quality of the side we were up against.

"We came in at half-time and said they were there for the taking."

Rugby director Ian McGeechan, who had Dallaglio and inside centre Dominic Waldouck sin-binned in the second half, said the blend of youth and experience saw his side through.

"We tried to balance the experience with youth and put some of our young players into this cauldron," he said.

"There is a balance between that experience and youth and it's always good to know you are playing alongside players who've been in every major tournament in the world, at both international and club level.

The impact that we had in the first half didn't come out in the second half Leinster coach Michael Cheika

"We played well both times with a man down. It sometimes focuses the mind for the players on the field.

"The pack were very good keeping the ball at that time and we defended superbly."

Leinster coach Michael Cheika was unhappy with how his side were blown away in the second period after going in at the break just 13-10 behind.

"We are bitterly disappointed," he said. "We lost a really good opportunity.

"We put ourselves in a really good position at the break and let it go. We gave everything but we didn't play to our ability in the second half.

"The impact that we had in the first half didn't come out in the second half.

"We knew they would run direct at us because they are very strong support runners and when you let them go through at the first point of contact you open the door. That caused errors.

"They came out firing with 14 men and took it to us. They deserved to get the points they scored at that time."
