Robin van Persie has completed his move to Manchester United.
The Red Devils confirmed they had agreed a fee with Arsenal on Wednesday evening, and after a medical yesterday the final elements of the transfer have been wrapped up.
The deal has been done in time for Van Persie to go straight into the squad for Monday's trip to Everton.
United announced in a statement: "Robin van Persie has completed his medical, agreed personal terms and signed for Manchester United on a four-year contract until June 2016."
United boss Alex Ferguson said: "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" - Alex Ferguson
Van Persie said it was an "honour" to sign for United.
He said: "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."
Ferguson told MUTV: "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."
Ferguson admitted he thought it would be impossible to get Van Persie to sign, but had to make an attempt when the striker did not sign a new contract with the north London club.
"It has given everyone a lift," said Ferguson.
"I have a complication to my life (selection). I don't know how I managed in 1999.
"They can gel together. Robin's best position is furthest up the pitch. The most important thing is to win what we want to win. These players can help us to do that."
Ferguson revealed he was still looking at a new signing for "one more position" but "only if a certain player came available".
