The Ireland centre has travelled to France after being named in the starting XV alongside midfield partner Luke Fitzgerald.

But O’Driscoll faces a fitness test on a hamstring injury, with Felipe Contepomi ready to replace him at Stade Pierre-Antoine.

Victory for Leinster would see them tighten their grip on Pool Two, extending their current six-point advantage over 2007 European champions Wasps, who host Edinburgh on Sunday.

Leinster beat Castres 33-3 in Dublin last weekend, but technical consultant Alan Gaffney accepts there are areas for improvement.

“There is no doubt that we probably played the game a bit narrow at the weekend. That is something we have addressed again,” he said.

“We have got the ability, we train and we know what we want to achieve. We put a few things together that we were happy with, but not enough.

“In terms of the passing last week, it was one of the worst performances that we have put in this year. We work on it every training session so there is no real reason as to why it happened.

“A lot of the passing was thrown into the body, which is more a timing issue. By passing the ball the way we did, into the body and into the shoulder, it took all the pace out of what we were trying to do.”
