Brian O'Driscoll says Leinster needs to test a tired Wasps side to make things as difficult as possible for the opposition in the final game of their European Champions Cup pool.

A win for Leinster at the Ricoh Arena will guarantee top spot but it will be a difficult challenge, given Wasps' improved form. 

The English side are coming off the back of an energy-sapping win over Harlequins and Off The Ball's guest presenter believes Leinster can use that to their advantage.

"[Wasps] will have talked about not surviving that for a second week on the trot. You look at all the stats of Leinster in the Pro 12 being the team that leads in carries, possession and is able to bring teams through phases, multi-phase, eight, nine, ten phases on numerous occasions ... that's going to test tired bodies. If Leinster are able to do that and get that semi-tired pack moving around a fast track in the Ricoh, I think that's where the key lies for them," said Brian

Alex Lowe of The Times joined Ger, Brian and Colm on the line and described Wasps as a "resurgent force in England, and they hope in Europe as well".

Highlighting the confidence of a club that have moved base from London to Coventry, he sees them as a big challenge for Leinster to overcome.
