Gatland: Biggar impact

The 20-year-old will win his fourth cap when Wales continue their autumn internationals by tackling Samoa in Cardiff on Friday night.

The Ospreys player will take the spot of the vastly more experienced Stephen Jones - almost 12 years Biggar's senior - for Wales' first fixture against Samoa since 2000.

And Wales head coach Gatland believes Biggar, who made his Test debut during last year's autumn series, has a glittering future, and said: "We need to look at options at 10. Dan has been playing well for the Ospreys, and we want to continue with his development. We see him as a player who is the next generation of number 10s in Wales."

He added: "He has shown all the right signs of a young 10 who is mature beyond his years.

"We think he is going to have a significant impact on Welsh rugby."

Gatland has made five changes from the side beaten 19-12 by New Zealand last weekend.

Cardiff Blues' 21-year-old flanker Sam Warburton is among the players called up, winning just his second cap.

Warburton takes over from Blues colleague Martyn Williams, while one other switch up front sees a start for Ospreys hooker Huw Bennett.

Behind the scrum, Biggar, Blues wing Tom James and Sale Sharks scrum-half Dwayne Peel all start as respective replacements for Jones, Shane Williams and Gareth Cooper.
