Just saying Rafa on clay is about as nightmare as a match up for Fed as you can get. Put prime Fed in 90s and on grass vs Sampras I think Fed can beat him...same goes for US Open, Fed is best hard courter in history. Clay....ain't no Nadal there, so Fed will surely have a much better chance of getting a FO. AO...Agassi was missing for prolonged periods of time and his best results there came a bit later.
No joke, Fed would have won a GS...wins AO and FO takes out the toughest challenge Sampras in W, and then the USO is done.
Roger Federer. Paolo Maldini. Tom Brady. Wilt Chamberlain. GOATs.
