G.O.A.T.
The primary guy he is chasing (Sampras) never won there, and didn't even make the finals (though he did make the semis, which people seem to forget).
Fed's made a semi and 2 finals, made a lot of Masters Series clay finals and won a few clay Masters, so it's not like there is any issue about his proficiency on clay.
And, almost all the other contenders for GOAT have surface gaps in their Slams (Borg - Hard) (Laver - hard, since the other three majors were on grass) (Sampras - clay).
