With Robin van Persie struggling to overcome a thigh problem and Wayne Rooney mixing an outstanding contribution to United's difficult campaign with a number of injury-enforced absences, De Gea has arguably been the most consistent performer in David Moyes' debut campaign as manager.
Not bad for the 23-year-old, rated no better than number five for his country and with little change of breaking into the Spain squad that will defend the World Cup in Brazil this summer.
There has not even been concerns raised over De Gea's ability to handle the physical side of the English game, aired so forcefully during the former Atletico Madrid man's first two seasons in the Premier League.
"I am pleased with my contribution so far," De Gea told MUTV.
"I feel very settled here and I am happy with the way I am playing.
"I am still learning and improving all the time. That is important.
"I hope to carry on doing that and keep my spot in the team."
By his own admission, De Gea undergoes a character change when he goes out to play.
Laid-back off the pitch, he is fully focused off it.
And while he still prefers to communicate in his native tongue - certainly with the media - De Gea has learned to get his point across.
"It is important to be honest," said De Gea.
"Off the pitch I like to be friendly and enjoy people's company but when I am on the pitch I am a lot more focused and concentrate totally on the game."
Until the New Year's Day home defeat by Tottenham, De Gea seemed to be getting in tune with his defenders.
The loss has halted United's momentum to an extent, although De Gea feels there are enough encouraging signs for the club to be optimistic for the future.
"We have picked up plenty of momentum as the season has developed," he said.
"It was a real shame we couldn't get three points against Tottenham but we are playing well now.
"We need to keep performing and win as many games as we possibly can."
Nevertheless, it seems improbable United can retain their Premier League title, with a top four berth the only realistic hope.
It places more emphasis on the cup competitions. And as a relative newcomer to Old Trafford, De Gea is among the vast majority at United never to even play in an FA Cup final, let alone actually win the competition.
Sir Alex Ferguson never wasted an opportunity to underline the importance of a tournament United have won more often than anyone else.
And with home advantage in Sunday's third round tie with Swansea, De Gea sees no reason why they should not progress.
"The FA Cup is a competition with a lot of history," he said.
"There is a lot of romance associated with it and it would be terrific to win it.
"Being at home is a boost because we will have so many fans behind us.
"Still, Swansea are a tough side and it will be a complicated game for us."
