United face Sheffield United on Wednesday as Solskjaer’s side line up at Old Trafford for the first time since winning the Manchester derby on March 8.
The Reds marked their opening match since the coronavirus lockdown with a 1-1 draw away to Spurs in the Premier League on Friday but De Gea was heavily criticised by former United skipper Roy Keane for letting Steven Bergwijn’s shot slip through his fingers.
United manager Solskjaer, a former Old Trafford team-mate of Keane, defended his goalkeeper, however, during a pre-match press conference on Tuesday.
“David is the best goalkeeper in the world,” he said.
“He’s conceded two goals in the last seven games he’s played for us. There’s two games against City, Chelsea, of course Tottenham, Everton. Two goals in seven games, we’ve gone on a run not conceding goals.
“The Everton one is a freak one, maybe. This one, he cannot save it. He makes great saves, he wins games for us.”
De Gea is set to start against the Blades, when Dean Henderson will be unable to face his parent club due to the terms of his loan deal.
