David De Gea should have saved Mason Mount goal ‘100 times out of 100’, says Manchester United boss Ole Gunnar Solskjaer

Goalkeeper was at fault for two of Chelsea’s three goals in their 3-1 victory over Manchester United that has seen calls increase for Solskjaer to replace the Spaniard

Manchester United's David De Gea should save Chelsea's second goal "100 times out of 100" according to manager Ole Gunnar Solskjaer after errors by the hapless goalkeeper saw his side suffer a 3-1 defeat in the FA Cup semi-final on Sunday.

The Spaniard was at fault for Chelsea's opener by Olivier Giroud in first-half stoppage time and then compounded that error by inexplicably allowing Mason Mount's shot to squirm through him and into the net early in the second half.

It continued a worrying downturn in form for De Gea but Solskjaer backed his first-choice keeper.

"I can't speak for David De Gea's confidence but he is mentally very strong," Solskjaer said. "He knows he should save that one 100 times out of 100 but that's football for you."

Second-choice Sergio Romero had been United's keeper in every round of the FA Cup so far this season, but Solskjaer opted to switch it for the Wembley clash.

"I made the decision to play him (De Gea) and mentally he was ready for it," added the Norwegian.

Solskjaer added: "Obviously everyone has to perform and everyone has a chance every time we perform to stake a claim in the team.

"David knows he should have saved the second goal but that's done now. We've got to move, we've got to look forward to Wednesday (against West Ham in the Premier League).

"It's hard for a keeper to make amends, apart from David making two or three fantastic saves after. But you see Brandon (Williams), for example - the character he shows. He plays a square pass into Mount, he probably feels a bit responsible and the rest of the half he was absolutely outstanding.

"The kid has been out for a while, not played, out with an eye injury and his character and personality out there, he kept going, kept going. It's so much easier for outfield players.

"David showed (his character) in the rest of the game with a few good saves, but he knows he could have saved that one."

Solskjaer also surprisingly left Anthony Martial, Paul Pogba and Mason Greenwood on the bench and his team never really got going against a Chelsea side who could have won by more.

In defence of his team selection, Solskjaer's team face a crucial week in the Premier League as they try to nail down a top-four place and a return to the Champions League.

"There is no time to feel sorry for ourselves, we have two games this week and then the Europa League. We will get our heads ready and our legs ready and go again," he said.

"They (Pogba and Martial) have played a lot of football so it's just about freshening up the team but also about giving them the chance to make a difference when they come on."

Solskjaer had some reassuring news about their Ivorian defender Eric Bailly, who was carried off after a first-half clash of heads with team mate Harry Maguire -- an incident Solskjaer said distracted his players.

"He is hopefully fine, he had a cut on his head but hopefully he will be fine," he said.

To compound United's misery Maguire scored an own goal before Bruno Fernandes converted a late consolation penalty against Chelsea, who will face Arsenal in the final.
