"I'm looking forward to putting a difficult summer behind me and working hard," said De Gea. "I am delighted to be starting this new chapter in my United career. "Manchester United is a special club and Old Trafford is an ideal place for me to continue to develop."
De Gea has not played for United this season as manager Louis van Gaal felt he could not focus amid interest from Real. Had he not signed a new deal, De Gea could have opened talks in January about a free-transfer move to Madrid for next summer. Van Gaal said he was "very pleased" the goalkeeper "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," added the Dutchman.
De Gea has made 175 appearances for United since joining the club from Atletico Madrid in 2011 in an £18.9m deal. He made several high-profile errors in his first few months in England, but has been in the Professional Footballers' Association Team of the Year in two of the past three seasons. United host Liverpool at Old Trafford in the Premier League in a 17:30 BST kick-off on Saturday, their first game back following the international break. Analysis BBC Sport's Simon Stone: "The deal De Gea has signed is the same one that was on table in the summer.
When the move to Real Madrid fell through, United approached the De Gea camp to ask if he would sign. "It has been stressed to De Gea by various people, including manager Louis van Gaal, that he is an important part of the club's plans. "United are not saying if there is a release fee in the contract but point out if Real wanted De Gea at the end of the season they would have to pay, whereas previously they would have got him for nothing. "They are stressing the deal has been done in good faith." Marca football writer Juan Castro: "For the fans, it's surprising - a player who just 12 days ago was about to sign for Real Madrid is now renewing his contract with Manchester United. "It's difficult to say right now if Real will try to sign him again. After what happened in the last minute of deadline
day, everything is possible. "Real president Florentino Perez still wants De Gea, but now he has another enemy - Manchester United - even bigger than before. This enemy is bigger and bigger every day and Florentino Perez knows that."
