De Gea, 28, has been putting in extra work to improve his skills with the ball fired back towards him.
The Spanish goalkeeper has had coaches working with him since he came back in the summer for pre-season.
An Old Trafford source told The Sun: “He has been training exclusively with his feet, at least half-an-hour at a time.
“The coaches have him fired repeatedly with ball returns under pressure with various passing options.
“They are also doing it because of the recent new rule changes of allowing two defenders inside the penalty area at goal kick.
“He has been clipping balls beyond the 18-yard box and into the full-backs and has worked well so far."
