IMO Rafael Nadal is one of the greatest competitors of all time in tennis, and arguably the GOAT on clay. His 2008 season was unbelievable; he finally dethroned Federer in one of the best matches of all time and became the first man since Borg to win the French and Wimbledon in the same year. He continued his dominance at the Australian Open and proved he was one of the best on (slow) hardcourt as well. Unfortunately his kneed didn't hold up and we all know the rest of the story. Although he came back and reached the semis of the US Open, his groundstrokes don't have the same penetration anymore. Although I'm a big fan of Federer, I truly hope Nadal will return to peak form next year, but I doubt it. I think the start of 2010 will be critical; if he doesn't win the French next year, that might prove the final blow. Another injury could be too much as well. What are your thoughts on this? Will Nadal regain his 2008 form and maybe become No. 1 again, or are his best days behind him?
