very interesting, great mentality and absolutely admirable how much work Fed puts on his game and his fitness
that's what makes him the champion he is
Definitely the most underrated part in him. Haters keep insisting on his talent
, that he was "born with it" (implying he's lucky and deosn't really deserve his success, compared to less talented players that work their ass off and still aren't that successful). Fed wouldn't be "Roger Federer - GOAT" without a true and smart dedication to every aspect of his game, and fitness is definitely a huge part of it, and Pierre Paganini and him have done wonders in the past and are still looking for improvements (despite their already amazing success).
