why is federer top3??
the same reason he is the best ever, the question should be, how can federer be top3 at age 33 and still make a run for the most important titles
cause hes the most complete player out there, he hasnt got isner serve, but hes got a really top serve, he doesnt have djoko backhhand or nadal consistent forehand spinned ball, but he has one of the best forehands out there and an amazing backhand, let alone the other aspects of the game, like movement, hes a master of movement
to be honest i think he only cannot be number 1 again because i always feel something lacks on him in respects of mentality, he got used to be so much better than most on tour that he didnt evolve in him trough the years that "animal" mentality like djokovic developed or nadal "inner super tough mentality" have to bypass tough situations.
he doesnt care anymore losing to nadal, and even to djokovic.. he simply would not run that extra mile, and i dont know why, but he never did.Thats a reason he didnt win nadal much more often, mentality problem, lack of belief, or else he could definetly still be number 1, i mean, you just need to see him play to understand thats a different kind of music youre "listening" to
