It is logical for Federer fans to hope for Nadal to win the Slam race , because Federer has Other achievements which can be compared to Nadal and hence Federer will get an equal recognition whenever there is GOAT debate .
Federer is greater at 3 Slams compared to Rafa ,
Fed has 310 weeks at Number one , Rafa has 210+
Fed has 6 WTF , Rafa has 0 .
Fed has 11 Harcourt Slams , Rafa has 6
Fed has 8 WB , Nadal has 2 ( and WB is most Iconic tennis tournament)
Rafa has also not won all Masters , same like Fed . So they can be compared there as well .
But if Novak wins the Slam race , then Federer will be left far too behind Djokovic in terms of achievements .
Djokovic has been the real successor of Federer's all court prowess and consistency .Infact , Djokovic went up a notch when it comes to these two aspects . He has become a master of all courts .
If there are no enmity between Federer-Djokovic , most Federer fans would have stood in Djokovic's corner as Djokovic has been the one to consistently reach finals of slams and masters and WTF back to back to back .
Just because of their personal grudge , both fan bases kinda warmed up to Nadal .
Fed himself would have been proud of Novak's consistency for which he was known for .
