Manchester United midfielder Ander Herrera has labelled his teammate David de Gea as the best goalkeeper in the world.

The Spaniard was once again at his best as he put in a Man of the Match performance, which included an impressive penalty save from Romelu Lukaku, in the FA Cup semi-final against Everton on Saturday, prompting plaudits from Herrera.

"What can I say? I am not objective - he is the number one in the world," Herrera told ManUtd.com.

"In England you know that, but in the rest of the world they think they have better goalkeepers, but I don't think so. When we win titles or trophies I think he will be more recognised.

"He has a special talent. When you are born with that quality and ability, you are so lucky. The rest of us humans, we have to work more. But what I like about him is that he is very calm, he has his feet on the ground. He doesn't change when it comes to these kind of games so I think he is number one of Spain and in the world - he is my friend so I am very happy for him."
