The 23-year-old ended months of speculation linking him with a move away from Valencia by penning a five-year deal with the west Londoners on Wednesday.
"[Villas-Boas] said he wanted Chelsea this season to play more attacking football, and that I would be a big part of that," he told the club's official website, www.chelseafc.com.
"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."
