Chelsea completed the signing of Juan Mata, the Valencia and Spain winger, on a five-year deal Wednesday night.
The 23 year old is Chelsea's fourth signing of the summer, following the arrivals of Oriol Romeu, Romelu Lukaku and Thibaut Courtois.
Mata could make his debut in Saturday's clash with Norwich City and moves to Stamford Bridge for a reported fee of £23.5 million (Dh141m).
Mata has given credit to Spain teammate Fernando Torres in helping sway him to join the English club. He said once the offer from Chelsea came, Torres "spoke with me and told me that playing abroad could be a very nice step for me."
Mata says he "never imagined himself leaving" but agreed to the move as the offer was too good for the Spanish club to pass up.
Valencia, one of Spain's most heavily indebted clubs, has made approximately €145 million (Dh872 million) in transfers since 2009 and remained in the Champions League.
Luka Modric, another Chelsea target, has been told by Harry Redknapp, the Tottenham Hotspur manager, to forget about a move and concentrate on playing for the north London club.
Modric missed Tottenham's 3-0 defeat against Manchester United on Monday after Redknapp decided the player was too unsettled by all the transfer talk to focus on the clash at Old Trafford.
Chelsea are believed to have made an improved £30m offer for Modric after having two previous bids rejected, but Daniel Levy, the Spurs chairman, is determined to keep the playmaker.
Modric did not train with his teammates yesterday, but could play in tonight's Europa League play-off second leg against Hearts.
"We will see how his hamstring is [today]. Certainly I'm looking to have him fit for the weekend against Man City."
Playing Modric tonight would mean he would not be able to play in the Champions League for Chelsea until February if he moves, but Redknapp is not worried about that.
"We are not in the Champions League so it won't affect us," he said. "I'm not bothered about anyone else. He is here, we love him, he is a great player so I need him back playing. He has to crack on with it now and I'm sure he will."
Redknapp is also hoping to seal a loan move for the Manchester City striker Emmanuel Adebayor and he believes Spurs fans will ignore the fact that he used to play for their hated rivals Arsenal.
"He is a good player and a real talent," Redknapp said. "If we can get him at it he could be a big success as he has a big point to prove.
Redknapp also expressed an interest in Liverpool's Joe Cole, a player he previously signed as an 11-year-old for West Ham United.
