Castres v Wasps: Teams

Wasps second row Simon Shaw has been passed fit to play in Sunday's all-or-nothing Heineken Cup clash against Castres after recovering from an infection in his elbow.

Shaw's return is the only change to the side that beat Leinster at Twickenham, with Wasps needing a maximum points win in France.

Victory with a bonus point should be enough to see Wasps progress as one of the best two runners-up at least - however they would go through as pool winners if Leinster then fail to pick up five points against Edinburgh.

"If you ask any of the players involved in 2006/07 Heineken Cup campaign everyone will tell you that Castres away was one of the toughest and most physical games of the season and we certainly expect the same on Sunday," said coach Shaun Edwards.

"They are a side with some big names and a very tough squad and beating Leinster at home we know that it will be no easy feat.

Focus

"We know that results across the last round could play a part in where we finish, but our focus is our game and our performance and we will be looking to build on the recent winning momentum and the fantastic game and day out that the club witnessed last weekend at Twickenham."

The game may be a dead rubber for Castres, however that has not stopped them naming a strong line-up for the visit of the defending Guinness Premiership champions.

France captain Lionel Nallet is named in the second row with former All Black Chris Masoe lining up on the flank. Among the backs, France scrum-half Sébastien Tillous-Borde is pushing for a place in the national XV and will be keen to put in a big performance.

Aussie Steve Kefu will start at outside centre.
