Federer still unbeatable!

Federer is still so fluid and devastating at his age. I think and say, to those who ask that he retire gracefully, why, when he is able to beat those 10 years his junior, effortlessly. He is playing the game in his personal capacity, and not taking anyone else's place on a team, like Sachin or Kapil did for years. He's around every year, and if you beat him, you can get past him, you deserve to win, because you are then the best, that year. 

Having said that, Federer's game has changed considerably in recent years, possibly due to influence of Stephan Edberg. He was quietly aggressive in the early 2000s, as much as the situation demanded then, became defensive and timid in the late 2000s, when he met Nadal and Roddick, and now has brought in a new aggression. He is not as amazing as he was before, but flashes of brilliance tend to amaze, time and again. He can't play long games, considering his age, so he tends to prefer shorter points. 

He may be a distant second in rankings, but that doesn't take away one bit from his infallibility with respect to all the other players. He may have some players who he hasn't been able to convincingly conquer, but overall, at this age too, he is unbeatable most times. 

And he is such an affable character, that you like him, even otherwise. And that adds to the aura that endears us to him. More power to him!
