Manchester City boss Pep Guardiola has warned Manchester United against letting Juan Mata come off contract.

Mata could leave United on a free transfer at the end of the season if a new contract is not agreed.

And Guardiola says: “He's an exceptional player, one of the players I like the most.

“From the period in Valencia, at Barcelona when I was there, we wanted to bring him but the problem was that we had a lot of midfield players that was the only problem.

“But, he's incredible, he played well for Chelsea and United and has a good restaurant in Manchester."
