The former world No. 4 Greg Rusedski believes that Novak Djokovic will be at the top of the rankings within the end of the year. Djokovic is currently third having 6,645 points, 455 less than Roger Federer and 2,285 less than Rafael Nadal.
Speaking on Amazon Prime, Rusedski said: 'Novak was by far the best player of this tournament. Del Potro found a way to get back into the match after being down 6-3, 3-1 and then he threw the kitchen sink at Djokovic - defensively he was quite incredible.
The way the court was playing, it was slow, the roof was closed. Everything was going in his favour as it was with Wimbledon in the semi-finals against Rafael Nadal. If I look at what Djokovic has done in the last months, in Miami he was in the wilderness and nowhere near the player he once was, then he hired the team, got back his trainer, got back his physio and that is why he is enjoying this moment so much.
Two Grand Slam titles this year - incredible feat. I think he’ll be No 1 in the world by the end of the year as well as the man to beat and don’t be surprised if he ties Federer’s record of 20 or gets even more the way he’s playing at the moment.
He tied his idol, Pete Sampras, with 14. Nadal is the next guy to catch at 17 and he’s only three back and then it’s the great man, Roger Federer. I just can’t see how you make a hole for him because you’re playing an opponent like Del Potro who hits the ball harder than anyone in the world, especially on that forehand side, backhand’s better, and still you can’t go through Novak.'
