Former Manchester United striker Dimitar Berbatov believes David de Gea has become complacent.

De Gea has come under even more scrutiny after his performance against Chelsea in the FA Cup semi-final, during which he was guilty for Olivier Giroud and Mason Mount's goals as United lost 3-1.

Dean Henderson, meanwhile, is now pushing for the No 1 spot at United after shining on loan for Sheffield United in the Premier League this season.

Berbatov told Betfair: "In my opinion, he is still one of the best goalkeepers in the world, regardless of the mistakes he has made this season. Every goalkeeper, even the greats of the past have all made mistakes throughout the years.

"It's David's job to evaluate his performance and I'm sure he knows that he's not doing well and he can do much, much better.

"I don't know what people want sometimes, he can come out and say 'yes, I made a mistake', but it's obvious that has happened, he can see it and I'm sure on the way home after the game he was regretting it, every footballer rewinds mistakes in their heads after a game.

"If United decide to bring back Dean Henderson from Sheffield United, I think that will do De Gea good; players need that competition and Henderson is doing tremendously well in my opinion.

"Henderson is 23, which for a goalkeeper is still very young, he's got a lot of football ahead of him, but you can see that he is hungry to play and I think the competition he could bring to De Gea could be the difference-maker, or breaker."
