Kalidou Koulibaly (Napoli)
Tipped to cost over £100million, Kalidou Koulibaly could be on the move this summer and has been linked several times with Man Utd.
The Senegal international seems like just the kind of Virgil van Dijk-esque signing the Red Devils need to compete with Liverpool and Man City next season.
Raphael Varane (Real Madrid)
Another big name centre-back, Raphael Varane is also said to be on MUFC’s radar this summer.
The France international’s Real Madrid future is in some doubt, so could follow team-mate Bale in swapping the Bernabeu for Old Trafford.
