New Saracens recruit Andy Farrell is confident his switch from rugby league to union will be a success.
Asked whether he had any fear of failure Farrell said: "None whatsoever. People might say it's a risk but I know what Andy Farrell's all about.
"I know the kind of effort I'll put in. If I was a betting man I'd back myself.
"I am very excited. I spent 14 years at a wonderful club in Wigan which I put my heart and soul into, but I'm like a kid in a sweet shop at the moment."
Farrell has moved to the 15-man code with a view to playing in the 2007 World Cup after English rugby union's governing body, the RFU, agreed a deal with Wigan.
Farrell said he was concentrating on his club career but admitted he was keen to play for England.
"Obviously, I would like to be successful at club level with Saracens and personally, if I can progress, I would like to be successful with England," he said.
"There is a lot of hard work to be done but a dual international is something special and that is an obvious goal for myself."
Farrell would not be drawn on what position he preferred to play, insisting it was up to his coaches to decide.
England coach Andy Robinson believes he can play at inside centre or in the back row, such is his admiration for Farrell's range of skills.
The 29-year-old admitted his decision to switch codes to rugby union was one of the most difficult he has ever made.
"I am Wigan born and bred, and the club have been my life since I was 15," he added.
"This was one of the hardest decisions I have had to make, but I feel that the time is now right for me to take on a new challenge."
Farrell has won 34 Great Britain caps, 29 as captain, and last year won rugby league's prestigious Man of Steel award for the second time after an outstanding Super League season.
