United host the Blades on Wednesday but Dean Henderson won’t be able to face his parent club due to the terms of his loan deal.
Ole Gunnar Solskjaer says “one day” Dean Henderson will become “England number one and Man United number one and it's up to him to keep developing."
David de Gea has come under immense scrutiny following his mistake in Manchester United’s 1-1 draw with Tottenham on Friday.
Critics believe the Spain International’s errors in the past year could see him lose the no.1 spot to Dean Henderson, who has shone while on loan at Sheffield United, but Solskjaer says it'll be a “different job” for the 24-year-old if he was playing for the Red Devils week in week out.
United host Chris Wilder’s side on Wednesday evening, with both sides keen to return to winning ways as the fight for a top-four spot rumbles on.
"It's a different job to be playing for Sheffield United and for Man United," Solskjaer said. "There's different, how do you say...he's got different roles.
"For me, the two years he’s had have been fantastic for his development. He's had to play with men, play against men, he's played in the Championship.
"He's played now behind a team that's played fantastic football and exciting football and, as the stats show, he's proven worthy of quite a few points at this stage.
"He's learning all the time. He's a passionate keeper that wants to be the best so he's developing, he's got good coaching there. I think one day he'll be England number one and Man United number one and it's up to him to keep developing."
