David de Gea has backed himself to overcome the doubters, despite the Manchester United goalkeeper facing a potential threat to his position from Dean Henderson next season.
De Gea's longer-term place in Ole Gunnar Solskjaer's side has come under scrutiny after he made a number of high-profile errors.
With De Gea, Sergio Romero and Henderson, who has returned from his loan spell with Sheffield United, to call upon, Solskjaer has admitted he cannot include three leading goalkeepers in his side next season.
But De Gea, who signed a four-year contract worth £19.5 million a year last September, says he is not worried about his future. "No, I trust in myself," he said. "I showed my qualities all these years, so I just keep available for the manager."
Henderson has attracted interest from Chelsea and other clubs after two successful years on loan at Bramall Lane, but he is reluctant to be De Gea's understudy next season.
It has created a quandary for Solskjaer who faces the prospect of having a £375,000-a-week goalkeeper on the bench if he opts to promote the younger man.
If Henderson is to be given his chance, it would also raise doubts about the future of Romero.
