Owen Farrell is confident he will thrive in his first start at fly-half for England against Wales at Twickenham.
Both teams have won their opening two games, while victory for Wales would secure them the Triple Crown on Saturday, following victories against Ireland and Scotland.
"It's a little bit of a change but I feel comfortable in the role," the 20-year-old told BBC Sport.
Charlie Hodgson's injury has prompted the positional change after Farrell started England's first two Championship games at Murrayfield and in Italy at centre.
Former England centre Will Greenwood gives his thoughts ahead of the game:
Interim coach Stuart Lancaster's bold selection in starting the Saracens man at fly-half has prompted inevitable comparisons to Jonny Wilkinson.
"I'm just happy to fit in anywhere I'm needed and to play anywhere for England. It's massively exciting," Farrell enthused.
He replaces injured Saracens club-mate Hodgson after he cut and sprained his left index finger in a freak training injury this week when he caught it on a team-mate's shirt.
With Farrell shifted in-field one place for a new new half-back pairing with Lee Dickson, the returning Manu Tuilagi will move to outside centre alongside Brad Barritt.
