Juan Mata has completed his £26 million move from Valencia to Chelsea and will be available for Saturday's Premier League match against Norwich at Stamford Bridge.
"Right from the first moment there have been good feelings all around me," Mata told Chelsea's official website after sealing his move. "Training has been great and the players are a great group to train with.
"Valencia was a big club anyway but I have left to join a bigger club and it is all about the opportunity to win trophies and I have that here."
Mata becomes the third Spaniard at the Blues, linking up with the aforementioned Romeu and fellow Spain international Fernando Torres.
"Fernando got me excited about the thought of coming here,'' Mata said. "He said it would be good for me here and that me and him together could be good. I also talked to my family and friends about it as well.''
While Torres and Mata's father, also named Juan, who played professionally for Burgos and Salamanca, had an influence on his move to west London, the winger admits it was manager Andres Villas-Boas that ultimately convinced him to make the switch.
"He said he wanted Chelsea this season to play more attacking football, and that I would be a big part of that,'' he added. "Villas-Boas is someone who won almost everything last year and we are both here with the idea of winning lots 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.
"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 former Real Madrid youngster scored 34 goals in 179 appearances during his four years at the Mestalla.
Mata, 23, is viewed as one of the hottest prospects in world football after back-to-back summers in which picked up the 2010 World Cup and the European Under-21 Championship title.
