Real Madrid have made it clear that they want David de Gea as part of the deal that would see Gareth Bale move to Old Trafford.
Manchester United were already linked with the Welshman last year and it seems manager Jose Mourinho is still interested in the former Tottenham Hotspur man.
The Daily Star has claimed on Saturday that the Spanish giants have identified the 28-year-old as the one to be sold in order to have the financial strength to sign Kylian Mbappe.
Real Madrid president Florentino Perez wants no less than £90million for Bale and wants to take advantage of the situation to finally bring De Gea to the club.
The Red Devils have already signed three world class players this summer.
Victor Lindelof in defence, Nemanja Matic in midfield and Romelu Lukaku in attack.
But Mourinho wants one more player before the end of the summer transfer window.
