Biarritz clash huge claim England duo

The English champions, who lead the Pool, are only two points ahead of the twice beaten finalists and know a victory would see them through to the last eight of the tournament.

Farrell insists that Saracens are under no illusions of the nature of Sunday's do-or-die clash with an unpredictable Biarritz side at Vicarage Road in Watford.

"It's a massive game for the club at the weekend and we're all looking forward to it. We've trained hard this week and we can't wait to get out there at Vicarage Road on Sunday," said Farrell."

Barritt echoed the thoughts of Sarries young tyro and labelled the clash a 'must-win' game for the Premiership side.

"There's no bigger game for us," said Barritt. "We know we must win if we want to continue to the quarter-finals, so the focus is definitely on the match.

"We know from playing them away that Biarritz are going to be a very tough side to face. They've got everything to play for and they've got some great players right across the park.

"We're looking forward to a huge game and want to put in a good performance when we're back at Vicarage Road."

Farrell along with the rest of the Saracens squad have spent a week in South Africa on warm weather training at Stellenbosch Sports Academy in preparation for the clash with the Basque outfit.

"It's been brilliant and we've enjoyed a chance to get away," Farrell said.

"The opportunity to train at the Cape Town Stadium was unbelievable and it was brilliant to visit Kayamandi.

"It was very special to see all the kids faces, as they played on the new artificial pitch that Saracens have funded. To go there and see first hand the good work the club are doing was brilliant."
