United are in a shoddy period of form after losing seven games out of their last nine, including exits in the FA Cup and Champions League.
It is a far cry from the initial brilliance that proceeded Ole Gunnar Solskjaer’s appointment as interim manager back in December last year.
After taking over from Jose Mourinho, the Norweigan oversaw a complete change in direction – with the likes of Pogba, Marcus Rashford and Anthony Martial performing magnificently.
But the bubble has now burst for the former Cardiff manager and the reality of the job has not firmly set in – with dressing room unrest rife at Old Trafford.
A number of players are said to be unhappy at United – with the prime suspect being Pogba.
The Frenchman has had his head turned by Real Madrid, with Zinedine Zidane keen to bring in his compatriot to kickstart his second reign in charge.
The Bernabeu boss has returned to Los Blancos, 10 months after resigning, and is being given huge funds to rebuild the side after a disappointing season.
Many United fans are beginning to turn on Pogba after several lackadaisical performances in recent weeks – but he is not the only one that wants to leave Old Trafford.
De Gea is also looking at a potential exit from United this summer and if the club fail to reach the Champions League next year, The Sun report he will be packing his bags.
Paris St-Germain and Juventus are tracking the Spaniard, who is also refusing to sign a new contract despite over a year of negotiations.
But Madrid are also in the market to look for a replacement for Keylor Navas, despite Thibaut Courtois signing only last year.
The return of Zidane has spelt disaster for the Belgian stopper, who is not fancied by the former Ballon d’Or winner.
Zidane is a much bigger fan of De Gea’s, but United are reluctant to see one of their best players leave – especially at a time where Pogba’s future is up in the air.
But ultimately, the Red Devils may not have a choice – as the 28-year-old enters the final year of his contract.
In the summer of 2020, De Gea’s contract will expire and United may have to cash in now rather than risk losing him or nothing.
