As focus pivots to Paris, Djokovic returns to the site of where he completed the career Grand Slam – achieved in 2016 – and the ensuing task of reeling in Roger Federer’s record haul of 20 major titles.
The Serb this week surpassed Pete Sampras for second most weeks as world No.1 and also has Federer’s mark of 310 weeks in his sights.
He is now guaranteed to hold top spot in the rankings for at least 293 weeks, to 9 November, leaving him a mere 17 weeks shy of the Swiss great’s mark.
“Of course I'm aware of the amount of weeks, and I don't know exactly the date, but I know it's going to be in probably the first or beginning of the second quarter of next year if I eventually maintain my No.1 ranking,” Djokovic said.
“I'm getting closer. I'm in a very good position, I feel like I have been also playing really well and been healthy, which is great.
“Yes… those are the two biggest professional goals that I have at the moment. So the historic No.1 ranking goal is something that is on the horizon, and I'm going to give my all and very best that I can possibly give in the next period to achieve that.
“But also, after that slams will be the big one, of course… I don't know what years to come will bring for me and just tennis and the world in general.”
