Manchester United risk losing David De Gea unless they make him the club’s highest-paid player alongside Alexis Sanchez in a deal that reflects his status as their outstanding performer over the past five seasons.

De Gea, 28, wants to stay at Old Trafford and the Spain No. 1 - arguably the world’s best goalkeeper - remains hopeful that the current contract stand-off will be resolved.

But having seen Sanchez join United from Arsenal last year on a contract worth around £500,000 a week once bonuses and image rights are factored in, De Gea believes his contribution in recent years warrants a similar deal.

De Gea will enter the final 12 months of his existing £240,000 a week contract this summer and he is understood to be holding out for a total deal worth around double that amount, having been named United’s player of the year in four of the past five seasons.

Juventus and Paris St-Germain are among the clubs monitoring De Gea’s situation and Thibaut Courtois’ struggles at Real Madrid following the Belgium goalkeeper’s £35 million move from Chelsea last summer have not gone unnoticed. Real have been long-term admirers of De Gea, whose proposed move to the Spanish giants in 2015 collapsed on transfer deadline day.
