Biarritz v Cardiff: Teams

Cardiff Blues will head to Parc des Sports with an unchanged team from last week, as they look to beat Biarritz for the second time in this season's Heineken Cup.

Director of rugby Dai Young admitted he was tempted to make changes for the trip, but with a full squad to pick from he opted against it in the end.

"We are looking for a better performance," Young said. "We were frustrated by Biarritz at Cardiff Arms Park.

"This is a key game for us in our bid to qualify for the quarter-finals of the Heineken Cup."

Victory would see the Blues with one foot in the quarter-finals, with games against Gloucester and Calvisano still to come.

Biarritz have made two changes to their starting side, both of which come in the forwards.

Wenceslas Lauret comes in on the blindside as Peïo Som drops to the bench, and Eduard Coetzee, who started on the bench last week, comes in at loosehead.

Having lost away to Gloucester and Cardiff Blues already, the French side can ill afford another defeat if they are to make the knockout stages.
