Real Madrid winger Arjen Robben says Valencia fullback Miguel is the toughest opponent he's ever come across.

The former Chelsea ace told AS: "I think my strongest marker has been Miguel, the Portuguese of Valencia.

"I met him in the Championship and the World Cup and I have had many problems playing against him. He's fast and aggressive and I have problems with him. He is a very good defender and he does well every time he faces me."
