Heineken Cup Pool Six leaders Cardiff Blues welcome back five Wales players from autumn Test duty, including in-form Andy Powell, for tonight's Arms Park clash against Biarritz.
The Blues boast a 100% record after two games, but Biarritz will be tough nuts to crack - home and away - during the next eight days.
“The Wales players are coming back battered, bruised and certainly mentally and physically drained, but they all desperately want to play in this game,” said Blues boss David Young.
“They were a big part of our efforts prior to the internationals. They helped us get where we are now, after a good start in the Heineken Cup.”
Blues’ fellow Welsh challengers the Scarlets are also in action tonight, tackling Ulster at Ravenhill.
Tomorrow, Newport Gwent Dragons visit Toulouse in Pool Five and the Ospreys entertain Pool Three strugglers Treviso.
