Former Barcelona goalkeeper Vitor Baia believes David de Gea still has parts of his game needing to be improved.

Baia is a fan of the Manchester United No1, but has spied a weakness in his game.

He told El Transistor: "De Gea is very strong.

"He dominates many situations, but for example he does not feel comfortable out of the posts, that must be something he corrects."

De Gea is set to be Spain's World Cup No1 this summer.
