Man Utd ace Ronaldo: I could hit free-kicks with old ball
He said: "It's not the boots that are important, it's the technique - the shot, the body, the style, the head and the hands.
"Some people think it's just about kicking the valve to get the flight correct, but it's not. The professionals know - it's not a mystery it's technique and I have this technique. 50 years ago the ball was different and so were the boots, but I think I would still score from the free kicks."
