I am surprised Agassi has not really got a mention. Agassi was renound for mental weakness and towards that start of his career did not take fitness remotely serious. However unlike these other talented players he still won 8 slams. Imagine what he could have won if he had been mentally stronger! Agassi would defentily be top 5 on my tallent list, possibly as high as 3. I think that McEnroe and Federer are the most tallented players. Rios and Safin are top 10 material, but not top 5 material.
