In my opinion the most talented player the most of the times reach the best ranking. There were several players with great talent that simply lost the right way. Personally I've never seen a player like Marcelo Ríos. His hands, his anticipation. Unfortunately God didn't gave him a regular brain. Does anybody remember the final against Agassi at The Lipton in Key Biscayne? Later, in 2002 I saw Ríos again versus Agassi inthe SF of the same tournament. He abandon he match in the 3rd set due a knee injury. He was self destructive and still a genius. Same case is Marat Safin. The only player that is a real threat to Federer in fast surfaces if he's in good condition (phisically and mentally). Does anybody remember a swedish player called Andreas Vinciguerra?
