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.

"The plan is that I can play on either flank or even in the middle playing in between the lines of midfield and attack. I like to keep the ball and use it well, I am an attacking player and above all I like to set up goals and score them also," Mata said.

"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.

Despite Chelsea manager Andre Villas-Boas declaring that he is pessimistic of signing Porto left back Alvaro Pereira, reports today claim the club be close to agreeing a deal for the player.

The full back is said to have told Porto that he wants to leave the club to join Chelsea and team up with Andre Villas-Boas again. Chelsea has failed in a £15m bid for the player but they are considering paying the full £25m release clause to buy Pereira's contract out.
