I think that he is a future world number one, and in the next few years he will defo be winning the US and Oz opens, and he also has a good shot at the French Open and Wimbo. Yesterday he proved just how good he will be by defeating Federer, to beat Roddick, Nadal and Federer back to back is an awesome feat. As of writing, I think he has defeated every1 (except Safin, and maybe Ferrero, but they are past it now). I could see Djokovic reaching the final of the US Open this year if he isn't on Fed's side of the draw, don't think he cud take Fed in 5 this year, next year though he could. Thoughts.
