Fiorentina GM Vincenzo Guerini says they're happy for Matija Nastasic over his move to Manchester City.

The Serb moved to City in a part swap for Stefan Savic.

"He's the son who everyone would like to have, has great humility and kindness," said Guerini. "The club has made a masterpiece deal, taking a lot of money and a player of the '91 class who City paid a lot for.

"Between Nastasic and Savic there is no difference.''
