Today, Novak Djokovic has moved into outright sixth place in the list of players who have spent the most weeks at No. 1 in the Emirates ATP Rankings.

Djokovic has been at the top of men's professional tennis for 142 weeks, one week more than Rafael Nadal, and now he has his sights set on John McEnroe on 170 weeks.

With a 4,310 point lead over No. 2-ranked Roger Federer in the Emirates ATP Rankings, if the Serbian were to maintain his firm grip on No. 1, which he reclaimed on 7 July 2014, he would start his 171st week at No. 1 on 9 November this year.

After that only Jimmy Connors (268 weeks), Ivan Lendl (270 weeks), Pete Sampras (286 weeks) and all-time leader Federer (302 weeks) are in front of Djokovic for most weeks spent at No. 1.
