Manchester City have signed French midfielder Samir Nasri from Arsenal on a four-year contract, Sky Sports News reported on Wednesday.
Local media reported the transfer fee for the 24-year-old was around 25 million pounds ($41 million). City officials were not immediately available to confirm the deal.
Television pictures showed Nasri signing autographs and posing for photographs with fans outside City's stadium as manager Robert Mancini finally got the player he has been wanting to sign for much of the close season.
Mancini has spoken of his frustration at the time it has taken to bring Nasri to Manchester, saying he would have preferred to bring him in earlier so he could get to work with his team mates before the season started.
The Italian will have to work out how to fit Nasri into a team that already boasts another playmaker, David Silva, and attacking talent such as Sergio Aguero, Edin Dzeko, Carlos Tevez and Mario Balotelli.
With City gearing up for their first Champions League campaign when the group stage starts next month, Mancini has plenty of chances for squad rotation.
City had already laid out around 50 million pounds in this month's transfer window on Argentina forward Aguero, French left-back Gael Clichy -- also bought from Arsenal -- and Montenegro defender Stefan Savic.
Since being taken over by the Abu Dhabi United Group in August 2008, City have spent an unprecedented amount for British soccer on buying top players.
In 2009, they bought Tevez, Gareth Barry and Emmanuel Adebayor. During the August 2010 transfer window their outlay was around 130 million on players such as Yaya Toure, Silva and Balotelli.
Under Mancini, who took over as manager in late 2009, City finished third in the Premier League last season, one place above Arsenal. City also won the FA Cup, their first major trophy in 35 years.
City have enjoyed a perfect start to the new Premier League season by winning both games to top the table on goal difference ahead of champions and neighbours Manchester United.
Nasri could make his City debut on Sunday when his new club travel to Arsenal's bitter north London rivals Tottenham Hotspur.
