Manchester City have completed the signing of midfielder Fernando from Porto.
The 26-year-old becomes the Premier League champions' second summer signing after Bacary Sagna and will wear the number six shirt next season.
Brazilian Fernando, who was not named in Luiz Felipe Scolari's World Cup squad, said:
"I am so happy to finally be joining Manchester City.
"I know there was talk of me possibly signing last January so I am delighted that the deal has now been done and that I am a City player.
"I’m looking forward to meeting my new team-mates and helping City to defend the title. It is a very exciting time to be part of this football club and I cannot wait to play in the Premier League.
"City fans can be assured I will give my all every time I play and I’m looking forward to many happy years in Manchester.
"I have enjoyed my stay with Porto and I thank the club and the fans for their support during my time in Portugal. Now I am ready for a new chapter in my career."
City almost bought Fernando in January but delayed the deal, confident of completing it in the summer.
His arrival will almost certainly signal the end of midfielder Jack Rodwell's disastrous two-year stint at Eastlands while Javi García, also signed in the same summer, could also depart.
