Valencia have confirmed that midfielder Juan Mata has reached an agreement with Chelsea and he is expected to be unveiled in London on Monday.

22795 - Chelsea win race to sign Mata

Mata, 23, had long been linked with a move to Arsenal, but with the expiration of a clause that allowed him to leave the club for €20 million last month, Chelsea swooped and have captured the Spanish international for a fee believed to be around €30 million.

A statement from Valencia read: "Valencia has reached an agreement in principle with Chelsea FC for the transfer of the player Juan Manuel Mata."

The deal is still subject to a medical, which Mata will undertake on Monday before being announced as a Chelsea player soon after.

Chelsea boss Andre Villas-Boas said on Saturday: "He's a player who scores and assists and he can add to any squad in the world. He's not our player but he's an interesting player ... a very good player.''
