G.O.A.T.
I assume Federer has 12 "real" GS then since first 8-9 he won against jokers like Safin, Phillapousis, Baghdadis, Hewitt two bagels, Gonzales, and so on?I've been saying all along that whenever anyone mentions Djokovic's 18 slams (if he wins the US Open) they'll mention that US Open he won without Nadal/Wawrinka/Federer.
That is 3 US Open champions missing from the draw. It will tarnish his legacy, whereas if he doesn't win the 18th slam he'll be fine.
