Robin van Persie has completed his £24m 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.

"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.
"We never thought we could get Van Persie. If you go back six months ago, I couldn't see us getting him.
"I thought Arsenal are not going to let him go. When I read he had refused a new contract, that is when we acted. It has been a long haul."
And Ferguson revealed he enjoyed negotiating with Arsenal manager Arsene Wenger.
"I can't elaborate but it was amicable," said the Scot. "Arsene knew the boy wanted to leave. He knew he wanted to join us. That made it a bit easier but not in terms of trying to reduce the fee.
"[Wenger] could run a poker school in Govan. He got a great price but we are also happy the matter is concluded.
"From the starting position when we first started negotiating, Arsene has done well."
Van Persie said there were "no hard feelings" against his former club
"It's just uncertain elements that we had a different view on. That's life. No-one is angry at me and I'm not angry at them," he said.
"It is always difficult to find the perfect match but I feel this is the perfect match.
"Manchester United breathes football. If
