The contract should give De Gea a substantial raise, rumoured to be to a weekly wage of £200,000, and is also rumoured to include a release clause of £30 million should Real Madrid resurrect their interest in the summer transfer window.
Florentino Perez this week ruled out a winter transfer for the goalkeeper. Real Madrid have also been spooked by the popularity of Keylor Navas amongst their own fans, so there is a remote chance that De Gea could stay at Old Trafford for more than just this season.
From United's official site:
David De Gea said:
I am delighted to be starting this new chapter in my United career. I have always enjoyed playing with these great players in front of our fantastic fans. Manchester United is a special club and Old Trafford is an ideal place for me to continue to develop my career. I'm looking forward to putting a difficult summer behind me and concentrating on working hard to improve and help my teammates to be successful.
Louis van Gaal said:
I am absolutely delighted David has signed a new contract. He is one of the best goalkeepers in world football. I am very pleased that he will be part of the team for many years to come. David made a very important contribution to our performance last season and he has been the club's Player of the Year for the last two seasons. He is a popular player who is keen to learn and enhance his game. At such a young age for a goalkeeper, he has many years ahead of him.
Both De Gea and Louis van Gaal are happy to put the distraction of the transfer behind them for this season, with De Gea needing games to secure a place for the Euro 2016, and also because of his general happiness with United and the city he lives in, despite also being attracted to a move to Real. De Gea is a popular member of the squad, so in addition to the improvement he brings over Sergio Romero, the rest of the squad will be pleased by his return to first-team action. It is believed he could make his season's debut against Liverpool on Saturday.
