Manchester United boss Sir Alex Ferguson has spoken of his admiration for Tottenham's strike-pair Dimitar Berbatov and Robbie Keane.
"He is a big, strong lad too. People don't realise how strong he is. He is well-balanced and hard to shake off the ball.
"Robbie Keane scored his 100th goal for them last Saturday and that is a terrific record considering Spurs have not really been that successful over the last few years.
"I have known Robbie since he was a kid at Wolves and remember my son Darren telling me about this young kid called Robbie so we know all about him.
"They also have Jermain Defoe as well so they have quite a potent force.
"But I think they will play Keane and Berbatov because it was interesting that, as soon as they got into a winning position against Arsenal on Tuesday, they whipped the two of them off."
