The former Real Madrid star has enjoyed some serious battles with United over the years and he canâ€™t wait to go toe-to-toe with the current crop of Old Trafford stars.
Raul said: â€œRooney is key for Unitedâ€™s attacking game. Itâ€™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.
â€œBut it is also necessary to stop Nani. He is now the engine of United and was a big signing for the club.
â€œUnitedâ€™s defence has quality and physical power, but I do not fear any rival.
â€œWe have watched DVDs of United and it is possible to beat them as long as we stay calm and use the ability we have."
