The United legend believes the goalkeeper is now indispensable.
This season Manchester United goalkeeper David De Gea has certainly come into his own. The Spaniard has been one of the best players at the club and was awarded with the October player of the month for his performances.
Of course it has not always been this way. When he first arrived at the club many were unsure of his talents, especially as he struggled for form.
He seemed to struggle adapting to the more physical Premier League standard and his handling was also called into question. However those problems have now been eradicated and many now believe he is the best stopper in the Premier League.
One man whose opinion has been changed on the player is Manchester United legend Gary Neville. The former right-back has previously criticised the stopper or his errors in his job as pundit for Sky Sports.
But now he feels the stopper is indispensable to the United cause.
Writing in his Telegraph column Neville said of the United custodian:
"De Gea is the player I would say Manchester United could least afford to sell. His improvement is enormous. In a Monday Night Football piece, a couple of years back, I pulled him up on his mistakes against Spurs, because I thought his errors would stop United winning the league. They had conceded 29 goals in 19 games.
"I see speculation that Real Madrid want to buy him for £25m. He would be the last person I would sell, as Manchester United manager, for any amount of money. After that Spurs game people remembered the criticism but failed to recall that I also said he could go on to be one of the world’s best. He just needed to develop that physical maturity and decision making. Now, you wouldn’t sell him at any price, and Manchester United should be looking to lock him down for the next five to seven years. He is winning games for them now."
The improvement of De Gea has been fantastic and Manchester United would indeed be stupid to let him go, hence why they are trying to tie him down to a new deal at the club.
Today he will hope to keep Hull City at bay, and where once there was trepidation, there is now belief that the Spanish keeper will do the business.
