Sinner-Alcaraz 'hurdle' becoming difficult to overcome, says Djokovic

Novak Djokovic said it was too soon to say whether he will play a full Grand Slam season next year, as he feels the strain of his 38 years against the newfound dominance of Jannik Sinner and Carlos Alcaraz.

The 24-times major winner lost to second seed Alcaraz 6-4 7-6(4) 6-2 in the US Open semi-final on Friday, marking the first year since 2017 that he has failed to reach a major final, the latest sign that his best days are behind him.

"I'm happy with my level of tennis, but you know, it's just the physicality of it," said Djokovic, who lifted the last of his four US Open titles two years ago.

"It will be very difficult for me in the future to overcome the hurdle of Sinner, Alcaraz, in the best-of-five on the Grand Slams. I think I have a better chance (in) best-of-three, but best-of-five, it's tough."

The seventh seed's showdown with the Spaniard 16 years his junior on Friday was billed as the hottest ticket in New York, where a rapt, celebrity-packed Arthur Ashe Stadium urged on the Serb two decades after his Flushing Meadows main draw debut.

He put up a reasonably clean performance, pulling out a few nifty tricks at the net with his trademark creativity, but could not match his opponent's intensity, producing roughly half as many winners as Alcaraz.

"I'm not giving up on Grand Slams," said Djokovic, who lost to Sinner in the Wimbledon and Roland Garros semis after retiring in his semi-final clash with Alexander Zverev in the Australian Open this year.

"I'm going to continue fighting and trying to get to the finals and fight for another trophy at least. But, you know, it's going to be a very difficult task."

His next stop on the ATP Tour will be in Athens and Djokovic said it was too soon to say whether he would play at Melbourne Park next year.

"At least at this stage of my career, I mean, I'm not thinking that far," he told reporters. "I still want to play Grand Slams, Grand Slam season, full Grand Slam season next year. Let's see whether that's going to happen or not."
