Real Madrid fullback Marcelo is backing fellow Brazilian Ronaldinho to rediscover his best for Barcelona.

Just over a week out from their looming clash, Marcelo said: "He's one of the best in the world. He is going through a difficult phase, but has a lot of goals and a lot of football to give."

The youngster added: "When I played in Brazil I looked forward to the Real Madrid matches against Barcelona. Now I have the chance to play in one, it'll be very important for me if I do."
