Rafael Nadal is thrilled with the revival of close rivals Roger Federer and Novak Djokovic as the big three continue to dominate the mens game.
Despite Stan Wawrinka, Andy Murray and Marin Cilic threatening to break the trios stronghold on the sport, they have shared 11 of the last 13 grand slam titles.
After Federer and Nadal retained their Australian Open and French Open titles respectively, Djokovic ended two years without a major by winning Wimbledon.
And ahead of the final major of the year at the US Open, Nadal has hailed the sports unpredictability.
(Roger) Federer won in Australia, (Novak) Djokovic at Wimbledon and me at Roland Garros, said the world number one.
All of us are at a high level, despite two months ago you were saying that Djokovic was a disaster, which I didnt believe too, and it says a lot about how the sport is unpredictable.
Its an exceptional coincidence that had never happened in history. We have been at the top for many years.
There are two options to explain it: either these players have been special or the ones behind were not enough special.
I dont know what is the right one, its up to you to say it.
But sooner or later it will change, either because others will have a higher level than us or because of how old we will be.
Nadals run at Wimbledon was ended by eventual champion Djokovic but his stranglehold on the world number one ranking was strengthened by Federers quarter-final exit to Kevin Anderson.
The Spaniard has few points to defend from the upcoming Canadian Open and Cincinnati Masters but is the defending champion from Flushing Meadows – venue for the final major of 2018.
