Serb has returned to the top of the list for the first time in two years, finishing off the 14th time last season.
Djokovic, 31, has been undergoing surgery in January, and has been trying to become a 22-year-old international after falling out of the quarter-finals of the Roland Garros in June, making him confident threatened by Wimbledon.
But he joined, joined Wimbledon fourth in the next month, the 32-man in Cincinnati, and won the third US Open Medal in September.
Despite the failure of the Paris Masters finalists Karen Khachanov on Sunday – he has ended 22 successes in the competition since he started the game at Wimbledon 31-2.
"Speaking about what I've been through last year, it's a great victory," said Djokovic, who beat Rafael Nadal from the first place in the world.
"I am very happy and happy, five months ago, it was very good and we respect the rank and way I played and felt a court."
& # 39; he has everything & # 39;
Djokovic is now three behind Nadal, featuring 17 Grand Slams and six-point Roger Federer's record 20.
However, he has time for his club – Federer has already celebrated his 37th birthday, while Nadal is 32 years old.
Djokovic enjoys a 25-22-point win over Federer and 27-25 against Nadal.
"Novak has everything to do with these games," said Juan Martin del Potro after winning the US Open.
Djokovic's power to grow in the ever-growing doubt, but the size of his heart has often led to water in previous days.
Wimbledon in 2007, retired from the semi-final of the Nadal tournament.
He also left for the 2006 and 2007 French Open, which opened the third round of the quarter-finals, while winning the Australian Open in 2009, where he defended the title, came out of the quarter-finals by describing Andy Roddick heat exhaust.
However, no one can answer the Australian Open in 2012, when he beat Nadal last Grand Slam at the end of the season, at 5hr 53min.
Djokovic first took over Melbourne in 2008, but was three years before he joined the second.
After Serbia scored the winner of the 2010 Davis Cup, he ran in the first half of 2011, having won 48-1.
Only the semi-finals of the French Open prevented him to be the only third to win Grand Slam history.
He finished in 2011 in 2011 with his unprecedented 706 defeat, 10 defeats and a trophy finish for the first time.
The returning Australian fans were followed in 2012 and 2013, despite three defeats to the last French defeat to reach 2016, when he won Roland Garros's success in his career Slam.
This year, Paris also became the first player to break $ 100 million (€ 87.8m) free of charge.
Djokovic is also unhappy that he will have new opportunities and win the tournament, bringing Boris Becker to part of his squad for the start of the 2014 season, despite being reunited with Marian Vajda.
In a court of law, Djokovic has long-time partner Jelena Ristic in July 2014. They have two children, Stefan's son and daughter Tara.
However, despite his successes, Djokovic looked overwhelmed and never considered a warm feeling like Federer and Nadal.
There are few who see less than the accounts of Djokovic.
It was postponed during the 2015 French Open to take eight minutes to health after the third hit Andy Murray, and Indian Wells next year, was criticized for the "men" to fight "get money" more than women's money.
"Statistics show that we have a lot of spectators to watch the tennis players," he said.
Wimbledon this year, he was hit by the supporters of the Court of Appeal to respect respect for the perpetrators and the schedules also felt that he had removed him from Second Court in the third round.
Despite the doubts, plaudits were generous on Monday.
"What has been the winner of Novak this season is to reduce one of the major sporting games," said ATP president Chris Kermode.
