Manchester City have confirmed they have finalised the deal with Atletico Madrid for the purchase of Argentina striker Sergio Aguero.
Aguero, 23, has signed a five-year contract, worth a reported £200,000 a week. No fee was confirmed by either club, but it is thought City have paid Atletico Madrid around £39 million for Aguero, eclipsing their previous high of £32.5 million for Brazil forward Robinho in August 2008.
He becomes manager Roberto Mancini's third signing of the summer, following the arrivals of Arsenal defender Gael Clichy and Partizan Belgrade's Stefan Savic.
A statement on the Manchester City website read: ''Sergio Aguero has become Manchester City's latest signing after the terms of his five-year-contract were completed today.
''The 23-year-old Argentinian international striker has moved to the Blues from Atletico Madrid, and is likely to be in the squad for this weekend's Dublin Super Cup tournament. He will wear the No. 16 shirt.''
Speaking after sealing his move, the striker said he was ready to play in the Premier League.
''I don't think I'll have too many problems settling into the team,'' he told City's official website. ''I'll obviously be doing my best to do what the manager asks and try to work the way he wants me to, and of course he will know how he wants to use me.
''Once I'm out on the field I will get to know my way round, but I can't say that for sure because I have not even made my debut yet. But I'm sure everything will be fine. I'm going to be relaxed about it.''
Aguero is the latest in a line of high-profile signings for City from the Spanish league, and he is already familiar with new team-mates Yaya Toure and David Silva from having played against them in La Liga.
''Of course the are great players, and yes I have played against them in the past but now they are here, in a team which right now is one of the biggest teams in England,'' Aguero added. ''So for sure they are great players and I'm lucky to be playing alongside them. I'm happy about that.''
Asked what he would add to the side, Aguero said: ''My style has always been to fight to the death for every ball, and give 100% in every game. Be concentrated to the maximum in everything I do; movement, running off the ball, winning the ball back and scoring goals. I'm not a player who can do everything, but I still have plenty to offer.''
Meanwhile, Argentina great Ossie Ardiles believes Aguero will be a ''wonderful'' addition to the club.
''He is quick, he is sharp and clever,'' Ardiles told BBC Sport. ''He can play as a lone striker, he can play with another guy and can come back and create things. He is very sharp. You give him one yard and this is it, he is gone. His vision is to score goals. If he has a little chance the ball will be in the net. I have no doubt whatsoever that he will be wonderful in the Premier League.''
Atletico also confirmed the deal minutes before City, and wished their former player a fond farewell.
''From this moment the Argentinian player ceases being part of our squad,'' said a club statement. ''The club thank him for his services during these five seasons and wish him luck in his new role.''
