Ospreys v Leicester: Teams

Wales international James Hook has been handed a huge opportunity at inside centre in the Ospreys' Heineken Cup Pool Three match against Leicester on Saturday.

The decision to use the British and Irish Lions star in the midfield means that Sonny Parker has been demoted to bench duty with Andrew Bishop shifting out one position to number thirteen.

Otherwise, head coach Sean Holley will be sending out an unchanged side for the vital fixture against the Tigers, in what should be a pulsating 80 minutes in Swansea.

Ospreys captain Ryan Jones said it was important to get the right result, given both the tight nature of the group and his side's 27-7 defeat by Clermont Auvergne last weekend.

"Saturday's game promises to be an great occasion, an exciting afternoon and a great game between two sides slugging it out for the big prize," he said.

"We know what we need to do, and that is get our own house in order after the disappointment last weekend, make sure we get the little things right, and with the necessary improvement in certain areas that we have been working on, we have to have confidence and faith in our ability and gameplan.

"We've certainly built up a rivalry with Leicester over the last few seasons, and all our games tend to be tight scorelines with not much to separate us, and they are always incident packed so I'd imagine it's going to be quite a spectacle."

Internationals back

Meanwhile, Leicester head coach Richard Cockerill welcomes back internationals Martin Castrogiovanni and Ben Kay to his squad.

Craig Newby starts in the back row after the knee ligament injury picked up by Tom Croft in the Tigers' win over Viadana last weekend and Lewis Moody returns at openside.

Castrogiovanni and Kay are named among the replacements alongside fellow internationals George Chuter, Aaron Mauger and Alesana Tuilagi.

The Tigers currently top Pool Three, just one point ahead of the Ospreys and Clermont, with everything to play for as the group stages reach a climax this weekend.

"It's a massive game, both sides know they can go through with a win or go out in defeat," said Cockerill.

"We are under pressure every week to perform. The difference this week is that if you lose you are out.

"Ospreys have got dangers all over the field, they have individuals that can break you down, so we have to make sure we are on top of our game.

"We've been playing well, we've had some decent results in recent weeks and we go there knowing what we have to do."
