Robin van Persie has completed his 24 million pounds move from Arsenal to Manchester United.
The Dutch striker, 29, has signed a four-year deal and could make his debut at Everton on Monday.
He said: "It's an honour to sign for Manchester United.
"I am looking forward to following in the footsteps of so many great strikers, bringing my experience and playing my part to help the team compete for the biggest trophies in the game. I can't wait to get started."
Manchester United manager Sir Alex Ferguson said: "The boy wanted to come. He turned down various clubs. If he hadn't told Arsenal he wanted to go to Manchester United, the transfer wouldn't have happened."
He added: "Robin is a world-class striker with a proven record in England and in European football.
"His talents need no introduction to our fans. He has scored a number of goals against us in some classic battles with his former club. His movement, finishing and all-round ability are outstanding."
A statement on Arsenal's website read : "Everyone at Arsenal would like to thank Robin for his contribution during his time with the club."
