And why would you be surprised? Fairly obvious isn't it? Federer is trying to keep Nadal at bay while Nadal is a FO win away from breathing down his neck. Being celebrities is the last thing on their mind. Now compare that to Sampras who was so far ahead of the pack in his era, he could afford to retire on his own terms and that's why he will always be in the GOAT discussion, even if he didn't win the FO. He dominated not just his era, but his generation, like no other. So put him back in please.
