What Novak Djokovic did is historic! Djokovic has won his 24th Grand Slam title by beating Daniil Medvedev 6-3 7-6 (5), 6-3 in the U.S. Open final on Sunday.

Now, this makes Djokovic’s record for the most major singles tennis championships won by a man. After Djokovic next is Rafael Nadal with 22.

Roger Federer, who announced his retirement last year, has 20 and broke a tie with Serena Williams for the most in the Open era, which began in 1968.

Like Djokovic, Margaret Court won a total of 24, but some of hers were earned during the sport’s amateur era.

And in an ominous warning to his rivals, Djokovic says he feels in good enough shape to add further slams to his roll of honour.

"I'm going to keep going. You know, I feel good in my own body. I still feel I got the support of my environment, of my team, of my family," he said.

"Grand Slams, I have vocalised that in the last few years, have been always the highest goal and the priority of mine in the whole season. I don't play as much in terms of other tournaments, so I try to prioritise my preparation so that I can peak in slams.

"Yeah, these are the moments and these are the kind of emotions that I motivate myself with every single day when I'm not playing a tournament. Yeah, occasionally I ask myself, 'why do I need this still at this stage after all I have done?' How long do I want to keep going?' I do have these questions in my head, of course.

Should we say that Djokovic is ready for his 25th Grand Slam? Because no wonder, the he's the Ultimate G.O.A.T of tennis, the unstoppable.
