Manchester City have confirmed the signing of French defender Eliaquim Mangala on a five-year-deal from Portuguese side Porto for a reported fee of £32 million.
Mangala is the second Porto player to make the switch to the Etihad after Manchester City Brazilian holding midfielder Fernando for an undisclosed fee.
Magala told the Manchester City website: "City is a top club in Europe, "For me, it was an important step to leave Porto and join Manchester City in order to continue my progress.
"I want to win titles and I believe I can do this. I am ambitious and this is why I am here."
The Frenchman added: "The fact that Fernando is here is better because I played with him at Porto but there is also other players that I know like Sagna, Clichy and Nasri."
Manchester City boss Manuel Pellegrini said: "He has all of the mental, physical, technical and tactical attributes to become one of Europe's very best defenders."
"Eliaquim is a player I believe will make an immediate impact in the Premier League, thanks to his physicality, his reading of the game and quality on the ball. "I think he will prove to be a great signing for us."
The 23-year-old is Manchester City's 5th signing of the summer. City have already signed Bacary Sagna on a free from Arsenal after the right-back refused to sign a new contract for the North London side. Pellegrini has also signed Wilfredo Caballero from his former side Malaga for a reported fee of £6 million.
Pellegrini has also recruited former Chelsea midfielder Frank Lampard on a 6-month loan from New York City FC.
Mangala was reportedly a target for Chelsea, but City were able to beat off competition from their rivals to land the highly-rated defender. He could now make his debut in their Premier League curtain raiser against Newcastle this weekend.
