De Gea: It's a mistake that can happen FIFA World Cup Russia 2018 - Portugal vs Spain He appreciated the support of his coach and teammates

Spain were held to a draw by Portugal in Sochi on Friday and many were pointing to David de Gea's humiliating mistake to gift Cristiano Ronaldo a second goal as a crucial moment in the tie.

Speaking after the final whistle, the Manchester United man explained what went wrong.

"I was late to put my knee down and the ball was screwed up, but I haven't killed anyone," he told the assembled press.

"The coach is with me, with all of the team, I'm calm. It's a mistake that can happen, a difficult ball.

"I'll keep training and doing things well, we have an important game against Iran and if we win it will be an important step to qualification.

"In the end we've drawn, not lost, the reaction was great. There it is, it's happened."

Overall, De Gea reflected on the result and said that he was impressed by the performance of his teammates.

"We had a good game, I'm happy with the team's reaction, I think we deserved more," he said of the result.

"Football is like that, things can happen. They're mistakes, those who put the gloves on and go out on the field know how difficult it is.

"I count on the support of the coach and my teammates to carry on and they show me that on the pitch.

"Football is like this, if you make a mistake you're very bad, if you play well you're very good. You have to get up."

De Gea will be out to prove a point against Iran on Wednesday in his next outing.
