Djokovic will certainly make an attempt to break the record. But the years are also starting to count for him and you can't play 20 tournaments a year. The competition is also big. In the days when Connors won all the tournaments, the tournament was much lower. Many people see Federer as the best player of all time, but Connors holds the record firmly. I don't know who the best female player of all time was. In the 90s that was undoubtedly the German Steffi grave. In the men's tennis in the 90s, the Americans Sampras and Agassi dominated. But I don't see it in the list either. I expect that Jack Sinner will also win the necessary tournaments. That is one of the most promising talents out there right now.
Yes, might be hard to chase that record, but for sure, as long as Djokovic is playing and it seems that he will have least a 1-2 years of his prime years ahead of him. He will be pushed by a lot of young players in the tour right now, but you can see that he holds himself very well with them. Sinner is just one, we have Alcaraz, unfortunately he is injured if I'm not mistaken.
Martina Navratilova, Chris Evert-Lloyd, Steffi Graf, Monica Seles, Martina Hingis and of course Serena Williams are the names that pop up in my mind as far as the ladies goes or at least the female tennis players that I was able to watch.
