Roy Keane's scathing assessment of David De Gea's goalkeeping credentials may have divided opinion but former Premier League goalkeeper Mark Schwarzer says questions need to be asked about the Spaniard.
De Gea allowed Steven Steven Bergwijn's shot to squirm through his grasp for Tottenham's goal against United on Friday, before a Bruno Fernandes penalty salvaged a point.
Schwarzer offered a more measured assessment than Keane's fury and said that the Spaniard could be under pressure for his place in the team once Dean Henderson returns from his loan at Sheffield United.
'Over the past 18 months David de Gea has made a considerable amount of mistakes and that's not expected from a keeper at that level,' said Schwarzer, who enjoyed an established Premier League career with Middlesbrough, Fulham, Chelsea and Leicester.
'For a top, world-class keeper, the maximum number of mistakes leading to a goal shouldn't be more than two a season and he's clearly made more than that.
'It will come to a head, when you've got Dean Henderson playing so well at Sheffield United and he's made it clear he won't sit on the bench.
'Is Henderson good enough to take the number one shirt at United? He has the potential.'
