Manchester City have reportedly identified Napoli defender Kalidou Koulibaly as a potential summer signing.

Pep Guardiola's side have just won their second successive Premier League title, but the Spaniard is looking to make defensive additions during the current transfer window.

The departure of Vincent Kompany means that a new centre-back is a priority, which has resulted in claims of a big-money bid for a target of neighbours Manchester United.

La Gazzetta dello Sport says that City are willing to spend in the region of £85m in order to win the race for Senegal international Koulibaly.

Napoli president Aurelio De Laurentiis has previously indicated that he has little desire to part ways with the 27-year-old, who still has four years left on his contract in Naples.

Nevertheless, the Serie A runners-up would likely consider cashing in on Koulibaly due to the possibility of signing a replacement for a much lower fee.
