Manchester United's legendary goalkeeper Peter Schmeichel says it is too early to replace David De Gea with Dean Henderson.
Reports have claimed the United brass are considering selling De Gea and replacing Henderson, who has impressed mightily with Sheffield United this season.
"There's no doubt about Henderson's potential, but he's played one season at a club who has had an unbelievable run in the Premier League.
"Henderson will need to show another season, like he's just come through, and then another one, and another one, in order to convince everyone that he is the right guy.
"There's a really big difference between being the No.1 at Bramall Lane and being the No.1 at Old Trafford, a really big difference. Even just being a player at those two clubs.
"I have seen a lot of guys come into Old Trafford with great reputations, goalscorers, and they haven't been able to do what they promised to do, with performances and talent.
The Dane added: "Just as an example, if Henderson makes a mistake – and I can only remember one he made against Liverpool - it's, 'Oh yeah, but he's young and talented and blah blah blah', because he plays for Sheffield United," Schmeichel added.
"If he makes that mistake at Old Trafford, for Manchester United, then it's headlines and it's all week until he plays the next game, where they question his ability to be the No.1.
"The pressures, the outside pressures, are so different. If you make a mistake playing for Sheffield United, well, fine, it's what happens, you're not expected to win every game.
"But you are when you're playing for the bigger clubs. So, let's see how he develops and keep an eye on him. But it's far too early.
"So the question: De Gea or Henderson? There's really only one answer to that."
