Manchester City coach Angelo Gregucci is confident over the talent of Matija Nastasic.

Gregucci commented on the exchanging of Nastasic with Fiorentina for Stefan Savic.

He said: "I am not someone who likes to pass quick judgement, so I won't say after a few months that we are dealing with a champion. We have to wait and see if Nastasic really can make history with this club.

"He certainly has great talent, but outlandish comparisons only risk damaging the lad's progress. As for Savic, he is a very interesting young player who has had some fitness problems."
