Novak Djokovic will on Monday set a new landmark of 311 weeks as world number one, surpassing Roger Federer whose hold on a record-equalling 20 Grand Slam titles is now firmly in the Serb’s sights.

The 33-year-old Djokovic, already the winner of 18 majors, has time on his side with Federer turning 40 in August. He is also a year younger than Rafael Nadal who also has 20 majors.

Nadal, currently at number two, has been at the top for ‘only’ 209 weeks in total although the 13-time Roland Garros champion can boast being a top 10 ever-present since April 2005.

He will, however, lose his world number two spot to Daniil Medvedev a week on Monday.

Djokovic, whose lone French Open title came in 2016, has comfortably more Australian Opens than Federer (six) and Nadal (one).

His Wimbledon total stands at five to Federer’s eight and Nadal’s two.

At the US Open, he has three to Federer’s five and Nadal’s four.
