The 22-year-old enjoyed an impressive second season for the recently crowned Premier League champions, and was named in the PFA Team of the Year.
It's not always been so easy for the Spanish stopper, though, after De Gea endured a difficult debut campaign at Old Trafford following his big-money move from Atletico Madrid in 2011.
But having answered his critics in style in 2012/13 with a string of impressive performances, the Manchester United man has attracted admiring glances from a number of clubs, including Barcelona.
"I'm happy in Manchester," declared De Gea in an interview with Spain U21s. "It has been a very good season, and the longer it goes, the better I'm there.
"I have a contract and hope to be at United for many years."
The summer departure of Sir Alex Ferguson - who retired after 26-years in charge of Manchester United - has inevitably raised some question marks about the future of a number of players.
However, De Gea remains committed to the cause, and is only thinking about his long-term prospects under new manager David Moyes, as the club prepare to defend their title in 2013/14.
"We are saddened by the departure of Ferguson, but in comes another great coach with a different style of play, so we will try to follow along the same lines and with the same tone," he explained.
"It's a shame that he went, he was great. But, now we have a new coach in David Moyes, who we still don't know. We're all waiting to get back there and see how it is with him."
