Wayne Rooney believes David de Gea will improve his game and eventually prove to be successful at Manchester United.
The 20-year-old goalkeeper moved to Old Trafford from Atletico Madrid this summer as a replacement for the retired Edwin van der Sar.
But he received criticism after making mistakes in his first two matches in English football, against Manchester City in the Community Shield and West Brom.
He then allowed Theo Walcott’s strike to go between his legs against Arsenal on Sunday, but saved a penalty from Robin van Persie earlier in the match.
Rooney said: “David is obviously a good shot-stopper.
“I hadn’t seen much of him before he signed but that was something I saw immediately.
“And his passing out from the back is alongside Edwin’s. He very rarely kicks long to a forward.”
He added: “He is still young and has probably got a lot to learn.
“But he is working hard and doing well in training.
“He is a strong character. After the Manchester City game, and then West Brom he didn’t seem to be affected.
“He was on the training pitch the next day, working hard.
“The last couple of games he’s done well for us and he will only get better the more he plays
