Novak Djokovic is wowing the world these days by what some call his "unprecedented dominance" of tennis this year. While what he's done this year is nothing short of marvelous, the truth of the matter is that Roger Federer did for four consecutive years what Novak's done in 2011.
And while his dominance in this particular year may as well match up to any single one of Federer's years between 2004-07, no one will ever repeat, year in year out, that frightening consistency that the Swiss master managed in his prime.
However, as they say, Father Time catches up with everyone, and it seems to be making up ground on the 30-year-old Federer as well.
The good news for him, however, is that his style of play can be managed for another few years, given that he doesn't grind out points and long rallies like Nadal and Djokovic appear to do. He prances around effortlessly on the tennis court, his grace reminiscent of a ballet dancer more so than a tennis player.
So instead of bringing about revolutionary changes to his game, here are the subtle tweaks that he needs to make in order to catch up to, and ultimately overtake, the seemingly peerless Novak Djokovic at the top.
