But they have made it clear any further discussions between the two clubs will also involve United’s pursuit of Madrid’s world-record £86m signing Gareth Bale – one which is looking increasingly likely to happen in the summer.
De Gea, United’s player of the season, is torn between a return to Spain and accepting a hugely-improved £200,000-a-week contract to stay at Old Trafford.
The club preferably wants an answer from Madrid over De Gea by the end of this month – and if he leaves, then United know they will be in a stronger position to negotiate a deal for Bale.
