According to you who has the best possibility to reach the final against Federer in US Open 2007? Assuming that Federer will be in the final considering the performances he showed in last three years. I have two candidates: Rafa and Djokovic. Also I want to see a match between Djokovic and Federer. According to me Djokovic is the second mentally toughest player on the tour after Rafa after I saw his matches against Hewitt and Baghdatis and especially the tie-breaks he played this Wimbledon showed that he is a winner. After last defeat to Federer in Dubai this year he stepped up very much beginning from Indian Wells and especially Miami Masters. I think he will not be like Roddick or Hewitt against Federer. According to me Federer will have very hard time against him the next time they meet. What do you think?
