Atletico Madrid midfielder Saul Niguez denies Spain teammate David de Gea is suffering a confidence crisis.

There's calls for the Manchester United goalkeeper to be dropped after conceding three goals in their 3-2 defeat to Croatia.

"When you put so much criticism on a player, it affects us all," Saul said at a news conference.

"Even if we say, 'No, it is not good for anyone that De Gea receives criticism, they should not be like that'.

"He is one of the best in the world. There may be times when you decide good or bad and for me it is unfair that you blame De Gea.

"I do not think he lacks confidence, he shows a tremendous personality, but what is generated, that negative energy, is not good for anyone. It would be best to change energy and talk about other things.

"If David concedes goals, I do not think it's just his fault, but everyone's, we all have to pay more attention."
