Manchester United boss Sir Alex Ferguson has drawn comparisons between Cristiano Ronaldo and Old Trafford legend Denis Law.
He said: "Denis had an incredible spring, which Ronaldo can relate to.
"Considering he was about 5ft 9ins, Denis was good in the air when you take into his account his height.
"He was lightning quick in the box as well. If anyone made a mistake, the ball was in the net.
"Denis and Ronaldo are great players. It is always hard to score a goal, I can assure you of that."
