Mata scored 43 times in four successful years at the Mestalla and has spoken of his determination to help Chelsea regain the Premier League this season.

"I want to adapt as quickly as possible to my new surroundings, my colleagues and this league, and I would love to win a trophy in my first season. If it can be the Premier League then great," the Spaniard continued.
