Man Utd in ‘constant contact’ with Napoli about Kalidou Koulibaly transfer with defender set to be sold

MANCHESTER UNITED are in "constant contact" with Napoli over the future of Kalidou Koulibaly, according to reports.

The Serie A club are believed to be resigned to losing their star asset this summer - with the Red Devils one of a trio of clubs hoping to pounce.

Ole Gunnar Solskjaer's side have persistently been linked with the 28-year-old in recent seasons without success.

But according to , this is likely to be the year in which Napoli finally flog their Senegalese centre-back - who is still contracted until 2023.

Club president Aurelio De Laurentiis is hoping to generate funds this summer - and wants to make around £113million out of Koulibaly and striker Arkadiusz Milik.

The former has evolved into one of the best defenders in the world since his 2014 move to the San Paolo from Genk - making 233 appearances for the Neapolitans.

United are desperate to land another centre-back, despite having splashed out £85million Harry Maguire from Leicester City last summer.

Phil Jones is expected to leave Old Trafford in the summer, while Chris Smalling could make his loan spell at Roma permanent - should United sign Koulibaly.

But to do so, they will have to beat off stiff competition.

Paris Saint-Germain and rivals Manchester City are also named as would-be suitors for the 6ft 1in stopper.

Koulibaly has been restricted to 21 appearances for Gennaro Gattuso's side this season, having struggled with injury.

The Senegal captain has been dogged by thigh problems that have seen him sidelined for 11 matches throughout this campaign.

He did, however, feature in every minute of his team's two Champions League matches against the Premier League's runaway leaders Liverpool - helping his side to a 2-0 win at home and a 1-1 draw at Anfield.
