Manchester United have until Tuesday to make a move, as the transfer window will be closing then.
United are attempting to acquire Bale from Real Madrid for close to £100m – £15m more than the Spanish side paid Tottenham Hotspur two years ago.
They have also gone after Bayern Munich winger Arjen Robben, for whom they are willing to pay £72.77m.
However, Bale is their top target.
United are keen to use De Gea in a part-exchange move for Bale, but The Express claim that De Gea’s move to Madrid is certain, while Bale to United is just a possibility.
