The Portuguese ace is well on his way of bagging his fourth Ballon d'Oro after a successful campaign with both his club and national team.

In a recent interview with Bild, Ferguson insists Ronaldo's passion and determination make him the best of his generation.

"He has an incredible desire for football; Cristiano is looking forward to each workout.

"He always wants to be better, to win. He especially loves these big games.

"During my time at Manchester United, Cristiano was the player who developed the most. Through much hard work.

"He constantly worked on his shooting technique, with the right, left, his heading ability, his bounce. His performance improvement is incredible. And what is remarkable, today's football is so athletic, so fast.

The ex-Red Devils coach added:

"Usually top players can only play for about five or six years at the highest level, then it's over.

"Cristiano has been doing this for over ten years. That makes him so exceptional.

"Every generation has its special footballer; Cristiano is currently."
