According to transfer expert Duncan Castles, Manchester City are leading Chelsea in the race for £70 million Napoli star Kalidou Koulibaly.
Duncan Castles said: “Gattuso has been told Koulibaly WILL be sold this summer.
“Koulibaly himself is open to that and is ready for a change of environment. He’s keen to move to the Premier League.
“Talk from Napoli is they could be looking at around £70m now for Koulibaly.
“The word from people close to Koulibaly is he thinks there’s a strong chance he will end up at Man City.
“They’re short on quality at centre-back and the only option Pep Guardiola trusts is Aymeric Laporte.
“In Koulibaly’s mind, it’s his more likely destination this summer.”
