Manchester United boss Sir Alex Ferguson has praised blunder ref Rob Styles for apologising to Bolton Wanderers over his penalty gaffe on Saturday.

Styles got another big call wrong on Saturday when he gave a penalty for Jlloyd Samuel's fair tackle on Manchester United winger Cristiano Ronaldo.

Fergie said: "Rob takes a lot of credit. It helps in terms of him showing some humility towards the game.

"It is good he has done it. It presents him in a different light. It shows he has character and is big enough to do it."
