Novak Djokovic stands alone.

Novak Djokovic may not have the same number of majors as Roger Federer or Rafa Nadal have, or the same number of Masters 1000's as Nadal has but what he did in Cincinnati last weekend in a well-documented league of his own.

He is the only one to have won the ATP Masters 1000's along with the season-ending championship, the ATP World Tour Finals and was the first man since Rod Laver in 1969 to also hold all four majors at the same time.

For the record Nadal has never won Miami, Shanghai and Paris Bercy while Federer is without Monte Carlo and Rome.

The ATP put together these videos commemorating Novak's achievements leading into the US Open where he and Nadal are viewed as favourites.
