England winger Shaun Wright-Phillips has signed for Chelsea, putting pen to paper on a five-year deal.
The 23-year-old winger's transfer from Manchester City will cost Chelsea £21m.
The England international will fly with Chelsea on Tuesday for their pre-season tour of the US as Jose Mourinho's side prepare for the new campaign.
Wright-Phillips spent most of Monday at Stamford Bridge - accompanied by his father Ian Wright - finalising personal terms and completing a medical.
After completing the deal and being handed Chelsea's number 24 shirt, Wright-Phillips said he was ready to fight for his place along with Damien Duff and Arjen Robben.
He said: "I never expected to be in anywhere and walk into any team to be honest with you.
"Competition is just healthy really and will help make me a better player. I just want to try and get some medals and be a regular part of the team. I want to play well for myself and for the fans, and for the coaching staff.
Chelsea chief executive Peter Kenyon said: "We're delighted that Shaun has joined us. He'll be a fantastic asset to the team and squad. This carries on the Chelsea policy of investing in young, top English talent."
Wright-Phillips was withdrawn from the City squad that travelled to Thailand on Sunday for the FA Premier League Asia Trophy.
He played for City in their friendly at Tranmere on Friday but withdrew from the side to play at Macclesfield on Saturday.
He claimed he was feeling unwell and as was being driven home he telephoned chairman John Wardle to inform him of his desire to speak to Chelsea.
Wright-Phillips previously insisted he wanted to stay at City, the club he joined in the summer of 1998 having been a trainee at Nottingham Forest.
He played almost 150 games for the club and was City's joint top scorer with 11 goals last season.
Wright-Phillips also made his England debut which saw him score against the Ukraine after coming on as a substitute.
