Andre Agassi said this quote
“ Walking to the net, I'm certain that I've lost to the better man, the Everest of the next generation. I pity the young players who will have to contend with him. I feel for the man who is fated to play Agassi to his Sampras. Though I don't mention Pete by name, I have him uppermost in my mind when I tell reporters: It's real simple. Most people have weaknesses. Federer has none. ”
