Manchester City are said to be on the verge of signing Fiorentina defender Matija Nastasic.
The 19-year-old made 25 Serie A appearances for the Viola last season, following his move from Partizan Belgrade.
He has also been capped twice at senior international level by Serbia.
According to the Gazetta dello Sport, City will pay Fiorentina £9.5m plus Montenegrin defender Stefan Savic in order to bring Nastasic to the Etihad Stadium.
Savic, 21, joined City from Partizan Belgrade 13 months ago, but he failed to impress during 11 Premier League appearances last season.
