Six Nations: Owen Farrell happy with fly-half switch

Owen Farrell is confident he will thrive in his first start for England at fly-half against Wales on Saturday.

Both sides are unbeaten in the Six Nations this season and Wales can secure the Triple Crown at Twickenham.

"It's a little bit of a change but I feel comfortable in the role," said the 20-year-old, who started England's first two Championship games at centre.

"I'm just happy to fit in anywhere I'm needed and to play anywhere for England. It's massively exciting."

Farrell replaces injured Saracens club-mate Charlie Hodgson meaning he will form a new half-back partnership with Northampton scrum-half Lee Dickson.

Between them, the pair have only four England caps but Farrell is confident they know each other well enough.

"We've had enough time. He's a brilliant player and one that never stops talking," Farrell told BBC Radio 5 live.

"He lets you know where he is and what he's doing and that bodes very well.

"I know the system inside out. I stepped in at 10 at the end of both games and before that in training we were always swapping around between 10 and the centres, just in case anything happened.

"I've been trying to do the things I do at the club here, trying to bring as much energy and as much information as I can.

"I'm not trying things I don't normally do, I'm just trying to do the things I do well."

Farrell added that Wales' hulking back-line held no fears for him and that he was banking on a lift from the crowd on his Twickenham debut for England.

"They're a very big back-line and they've been performing really well, with [Wales fly-half] Rhys Priestland guiding them," said Farrell.

"He's a massive player but they've got strike players all over the pitch, two very physical, ball-playing centres and massive wingers.

"But we're excited about it. You've got a lot more people behind you [playing at Twickenham] and you get a bit of momentum when the crowd really get behind you, you can grow another leg."
