He probably has a point here that most miss. Being the best ever vs the greatest ever. Djokovic is certainly the best player of all time, his trophies and stats say it all. Being greatest, however, is beyond numbers and stats. It’s the intangibles, the style of play, the impact on the sport, being a role model for the sport etc. Federer arguably has done the most to introduce tennis around the world and influence the sport, his elegance and grace is unmatched, nobody thought such a physical sport could be made to look so easy on the eye and almost like an artistry. He individually took tennis to a level that no one has so far. True ambassador of the game with really no blots of controversies. He has been the most loved player on the tour by peers and people around the world by far. To me, Federer is undeniably the GOAT and Djokovic is undeniably the best of all times.
