Manchester United legend Roy Keane says he's never been convinced by David de Gea.
De Gea conceded twice in defeat at West Ham just days after signing a new contract.
Keane said, "I'm not so sure.
Goalkeepers can make mistakes but I've always worried about him.
Every time I've watched him it's the character side of the game. He never seems to be commanding.
I never get the impression he's the type of character that puts demands on people around him."
