Sir Alex Ferguson insists he retains full faith in Ben Foster despite the goalkeeper's nervy display in Sunday's Community Shield defeat to Chelsea.
The 26-year-old was not at his best after being given the nod to start ahead of Tomasz Kuszczak in the absence of the injured Edwin van der Sar.
Foster will be disappointed he let Frank Lampard's shot beat him for Chelsea's second goal at Wembley, with Ferguson conceding it was not the most assured of displays from his keeper.
The Scot, though, believes Foster has all the attributes to become Van der Sar's long-term successor and will continue to back him unequivocally.
"Knowing Ben and the ability which he has, he should have done better with the second goal," said the Manchester United boss.
"However, it was his first big challenge. He has waited a long time, has had his injuries and in pre-season I spread the load between the three keepers, and maybe we did not have enough minutes for him.
"But the important thing is, knowing his ability, it means I do not have any worries about him."
