Sacrilige. Zidane was as good as any of them. His touch and vision probably the best of all time. Could tackle, head the ball, wasn't afraid to get stuck in(to the point of stupidity sometimes). Ronaldo has a long, long, long way to go to prove himself anywhere near the level Zidane played at for 10 years or more.
BTW Brazilians don't think Pele is the best player of all time. In their polls Garrincha usually wins...
