Biarritz stuttered to a 19-11 win against Viadana in Italy last weekend while Saracens gained a valuable bonus-point win over Glasgow.

The 2006 finalists have only lost one of their last 20 Heineken Cup matches at home, the quarter-final 7-6 loss to Northampton Saints last season and have registered US Eagle Takudzwa Ngwenya for this match, giving them extra fire power on the wing.

The visitors will be buoyed by their impressive start but considering Biarritz’s home record, a bonus-point defeat at the Parc des Sports Aguilera would seem like a minor triumph for Alan Gaffney’s side.
