Novak Djokovic still remains the favourite to win any tournament he enters and is capable of winning six more grand slams before the end of next year.

That is according to former Wimbledon winner Richard Krajicek, who told Stats Perform he considers Djokovic the sport's all-time greatest.

Djokovic won three majors last year and reached the final of a fourth, but he was knocked out of the 2024 Australian Open at the semi-final stage.

Jannik Sinner defeated the 10-time Melbourne champion in four sets before beating Daniil Medvedev in the final, seeming to usher in a new era for tennis.

However, Krajicek insists Djokovic is far from done as he continues to pick and choose which tournaments he enters. 

"Five or six years ago, I was wondering how long he's going to maintain his level, but he's still doing it," Krajicek told Stats Perform.

"He played very few tournaments last year and still managed to be number one. 

"I doubt that he's going to stay number one for long if he only plays 11 or 12 events because then you basically have to win every event.

"But for me, he's still going to win one to three grand slams a year, for the next two years at least."

Wimbledon was the only major at which Djokovic fell short last year as his streak of four straight titles at SW19 came to an end against Carlos Alcaraz.

Krajicek, who won the tournament in 1996, believes the 36-year-old remains the man to beat in this year's competition.

"For sure, at Wimbledon," Krajicek said when asked if Djokovic is the favourite. "The French Open and the US Open has more competition. 

"It's difficult as there are more strong, fit players like Medvedev, Sinner and Alcaraz. 

"That will be very difficult to win the US Open, but for me, he is still the favourite to win Wimbledon."

Djokovic won his 24th grand slam singles title when triumphing at the US Open last September with victory over Medvedev in the final.

The world number one is two in front of Rafael Nadal for the most majors won by a male in the Open Era, while the retired Roger Federer finished on 20.

On that basis, Djokovic is the greatest of all time in the view of Krajicek, who also cites his longevity.

"For me, he's the best player that ever played the game," the Dutchman said. "He has won every grand slam at least three times. 

"He's won 24 grand slams, and he's also won four grand slams in a row previously. Those are just incredible stats. 

"He's been number one for over 400 weeks, and I think Federer is the next one with about 310 weeks. 

"So, for me, Federer and Nadal are unbelievable players, but Djokovic is just a little level higher."
