The 22-year-old recently linked up with the Spain U21s squad for this summer's European Championships in Israel, and speaking to one of his country's publications, was asked to sum up his former side's season.
"To win at Madrid's Bernabeu in a final, I cannot ask for anything more because they also have qualified for the Champions [League] and have made a great season," De Gea reflected on Atletico's Copa del Rey final victory over Real Madrid in an interview with AS.
"Hopefully in the future I can return, you never know. It has been and will always be my home."
The Spanish stopper enjoyed a successful 2013/13 campaign of his own, as Manchester United reclaimed the Premier League title from bitter rivals Manchester City, in Sir Alex Ferguson's final season in charge at Old Trafford.
De Gea will return to Carrington to start pre-season with the Red Devils next month, and admits that it will be strange without the 71-year-old Scot, but at the same time is looking forward to working under Ferguson's replacement, David Moyes, who he hopes will deliver the same success as his predecessor.
"Obviously there will be a change, he was the coach for many years, many titles and many joys. Now comes a new coach I think it will continue in the same line of Sir Alex and dynamics will be similar.
"Playing for United, one of the greatest clubs in the world, is always a source of pride to me. Every time I pull the shirt on, I'm pulling on the history of this club."
