Manchester United coach Olli Gunnar Solchar confirmed that goalkeeper David de Gea should have faced Chelsea's second goal "100 times out of 100 attempts", after the team lost 3-1 in the FA Cup semi-final on Sunday.

And the Spanish goalkeeper missed the goal of Olivier Giroud at the end of the second half, then allowed Mason Mount's long-range shot to go into his net at the beginning of the second half.

The worrying decline in De Gea's performance continued, but Solchar continued to support United's first guard.

"We cannot talk about David de Gea's confidence, but he has a lot of mental strength," said Solchar. "He understands that he should have fought 100 times out of 100 attempts, but that's how football goes."

Sergio Romero - United's second goalkeeper - participated in all previous United matches in the FA Cup, but Solchar decided to use De Gea at Wembley.

"I made the decision to involve him (de Gea) and he was mentally prepared," said the Norwegian coach.

Some fans of Manchester United agreed that the Spanish goalkeeper de Gea - who was considered the best goalkeeper in the world - began to decline and lose confidence in himself, since Portuguese star Cristiano Ronaldo scored a goal in his goal at the 2018 World Cup in Russia, where he hit the ball at hand De Gea, but he turned it in his net instead of holding it.

Some fans said that after this ball, De Gea turned to goalkeeper Loris Carius, whose mistakes caused Liverpool to lose the 2018 UEFA Champions League final to Real Madrid 3-1.

David De Gea had one of the best seasons we've ever seen from a goalkeeper.

Then he had his Rob Green moment at the World Cup, and ... he became Rob Green
