The former Real Madrid star has enjoyed some serious battles with United over the years and he can’t wait to go toe-to-toe with the current crop of Old Trafford stars.
Raul said: “Rooney is key for United’s attacking game. It’s basic football, but we have to stop the ball getting to him in the area because he is able to create danger in any situation.
“But it is also necessary to stop Nani. He is now the engine of United and was a big signing for the club.
“United’s defence has quality and physical power, but I do not fear any rival.
“We have watched DVDs of United and it is possible to beat them as long as we stay calm and use the ability we have."
