Manchester United have been informed the price to sign Napoli defender Kalidou Koulibaly.

TMW says United are in contact with Napoli for Koulibaly and been informed they're prepared to sell.

Jose Mourinho is targeting a centre back this summer with Tottenham's Toby Alderweireld also on a list of possible targets as he looks to strengthen his back line.

Koulibaly is being touted as one of the best centre-backs in Europe and Napoli are demanding in excess of £70million for the 26-year-old.

He has also been linked with a move to Chelsea this past week.
