There's only one Ronaldo when it comes to the world's game. The World Cup's all-time leading goal scorer -- which includes names like Pele, Muller and Maradona -- never won a CL crown, but one magical night at Old Trafford reminded the world what a healthy and motivated Luiz Nazario da Lima was capable of when he scored a hat trick for the ages and left the Man U crowd in appreciative awe. It was one of the greatest single-game performances ever in Champions League. One of two men in history to win the FIFA World Player of the Year three times and member of the FIFA 100, Ronaldo saved his best -- as all the best Brazilians do -- for the World Cup. But Il Fenomeno's feats in the CL didn't lag too far behind.
