Manchester United have signed Nemanja Matic from Chelsea on a three-year contract.
The Serbia midfielder has departed Stamford Bridge after a three-and-a-half year second spell in west London, and has the option to extend his deal at Old Trafford for a further year.
He told the official Man United website: “I am delighted to have joined Manchester United. To work with Jose Mourinho once again was an opportunity I couldn’t turn down.
“I have enjoyed my time at Chelsea and would like to thank the club and the fans for their support. I cannot wait to meet my new team-mates and to start training with them.
“This is a very exciting time for the club and I am looking forward to playing my part in creating more history for this great club.”
