The Hull and Wales right-back said: "It will be a good experience. I've played against England, Germany, Brazil, so I've played against the best in the world.
"To do it week-in, week-out will be a big ask but it something I've always wanted to do.
"But I have the confidence in my own ability after playing for Wales.
"I support Liverpool so for me to go to Anfield will be a great occasion."
And Ricketts, 27, reckons joining the Premier League thoroughbreds proves he was right to turn down a career in showjumping.
The Hull right back's dad Derek is a former world champion and now boss of the GB equestrian team heading for the Beijing Olympics.
He added: "I come from a show jumping family and as a kid I had the chance to go into that. Until the age of 14 I rode but I stopped when it clashed with football.
"I don't have any regrets now, not after this. But a few years ago I was probably thinking I'd have been better off riding than football. To get to the Premiership changes all that."
