As expected, 21-year-old Scarlets centre Jonathan Davies has secured a place in midfield alongside Jamie Roberts, replacing nose injury victim Tom Shanklin.

Roberts moves to outside centre to accommodate Davies, while there are recalls for a quartet of 2009 British and Irish Lions, with wing Shane Williams, fly-half Stephen Jones, hooker Matthew Rees and flanker Martyn Williams all featuring after being rested against Samoa.

The one slight surprise sees scrum-half Gareth Cooper preferred to Dwayne Peel. Cooper started against New Zealand earlier this month, but Peel was among Wales’ best players during the 17-13 Samoa win.

Davies for Shanklin is the only change from the side beaten by New Zealand 10 days ago.

On the bench, there is an opportunity for uncapped Dragons flanker Dan Lydiate, while Ospreys centre Andrew Bishop - called into the squad as cover for Shanklin yesterday - is also a replacement.

Assessing his line-up, Gatland said: “Jonathan came on at inside centre on Friday when Tom Shanklin was injured, and he acquitted himself well.

“That’s his natural position. He plays there for his region and is comfortable there.

"Jamie is the more experienced player and more than capable of playing at 13, and we are looking forward to the continuation of the partnership from the second-half last weekend.

“With James Hook going so well at full-back, it was important for us to continue his international development in that position.”
