John Isner has faced Roger Federer, Rafael Nadal and Novak Djokovic several times. The former World number 8 was particularly impressed by the improvements of the 17-time Slam champion, who started 2020 by winning the ATP Cup, the Australian Open and the Dubai tournament.
Novak Djokovic's serve has been the most underrated part of his game mainly due to his mastery in the return game. Serving masterclass John Isner also rates Djokovic’s service as highly effective. “You actually don’t think about his service, which is kind of disrespectful to him in a sense, just because he does everything so well,” Isner said in an interview with the ATPTour.com.
“Djokovic spot serves it very well. He won’t necessarily hit it 130 miles per hour, but he’s definitely improved that part of his game,” Isner added. “He would even say probably six or seven years ago that his serve was a bit of a liability.
But now it’s not at all, and that’s why he’s the most dominant player in the game”. The American fears that it could be a while before tennis returns after the enforced break due to the international nature of the sport.
“It’s definitely different for tennis than for a lot of other sports. This is just my opinion, and I hope I am wrong, but I feel like tennis might be one of the last sports to get going again just because it’s international,” he told ESPN.
“It’s a tough spot for whoever is hosting whatever the first tournament is, whenever things get back under control. Countries and cities might have different rules and regulations about who can enter or compete.
It’s a big question mark for tennis right now, no doubt. It’s a big question mark for tennis right now, because our competitors are scattered all over the world”.
