Novak Djokovic has now spent 331 weeks as the world number one after the new ATP rankings were released on Monday.

The Serb is currently competing at the Tokyo Olympics and aiming to become the first man to win all four majors and the Olympics in the same season. This feat has only been achieved by Steffi Graf in 1988.

Almost 2000 points ahead of Russian Daniil Medvedev, who second on the rankings, Djokovic breezed into the third round of the Tokyo Olympics with a 6-4, 6-3 win over Germany's Jan-Lennard Struff.
