Manchester City have agreed a fee with Fiorentina for defender Matija Nastasic, according to reports.
Nastasic would become manager Roberto Mancini's second signing of the summer after Jack Rodwell joined earlier this month.
The 19-year-old joined Fiorentina from Partizan Belgrade in 2011, making 29 appearances for the Serie A side and scoring two goals.
Nastasic is also a full international, making two appearances for Serbia.
