Kalidou Koulibaly thinks there is a "strong chance" he will join Manchester City this summer, according to transfer expert Duncan Castles. Napoli centre-back Koulibaly is expected to leave the Serie A club in the next transfer window. Liverpool have also been linked with a move for the Senegal international.

However, Castles says Liverpool's priority is to sign a left-footed centre-back who can also play at left-back, therefore providing cover for Andy Robertson as well as being able to play in the middle of defence.

That would rule them out of the running for Koulibaly who is right footed and would complement the left-footed Aymeric Laporte at City.

Castles says Koulibaly knows City's need for a defender is greater than Liverpool's and the 28-year-old expects a move to the Etihad to happen.

However, Napoli are still set to ask for around €80million (£72.5m) for his services.

"Napoli's coach Gennaro Gattuso has been told Koulibaly will definitely be sold this summer and a replacement centre-back is coming in," Castles said on the Transfer Window podcast.
