Novak Djokovic is just one grand slam away from becoming the most decorated player in history and Feliciano Lopez believes "the numbers don't lie" when it comes to debating tennis' greatest.

Serbia's Djokovic equalled Margaret Court's record of 24 grand slam triumphs after defeating Daniil Medvedev in straight sets at the US Open earlier in September.

That made the world number one, aged 36 years and 111 days at the time, the oldest winner of the men's singles title at the US Open.

It was also Djokovic's third major crown of 2023, winning a trio of grand slams in a calendar year for the fourth time in his career,

Davis Cup tournament director Lopez, who had previously hailed Djokovic for featuring at the "unique" competition, suggested no one in history compares with the 36-year-old.

Asked by Stats Perform if Djokovic was the GOAT – greatest of all time – Lopez said: "According to the numbers, yes. The numbers don't lie.

"If you look at the stats, Novak is the best. So, I mean, what can I say?

"I think the numbers are very clear, not only by the fact that he's won 24 slams, but also there are other numbers and other statistics that clearly show he's the best player who ever played the sport.

"According to the numbers, I cannot say anything different."

Djokovic triumphed at the Australian Open, French Open and US Open, only missing out on a clean sweep of the majors after losing the Wimbledon final to Carlos Alcaraz.

As for Djokovic's chances for more major success going forward, Lopez believes the sky is still the limit.

"It's very difficult to predict honestly, but as long as he's feeling physically strong I think it's clear that his will in the last three or four years is to keep winning grand slams," Lopez added.  

"If he is able to sustain his physical condition for the next two years, I can fairly say that he can win, I don't know, two, three or four, but it's very difficult to say one number because this year, for example, he could have won all four.

"He won in Australia, he won in Paris, he was very close to winning Wimbledon because of that second-set tie-break, and he just won the US Open.

"You ask me how many grand slams you think he will win in the future when he just won three of them in the same year!

"I don't know, maybe three or four more is fair to say, but it's very difficult to predict."
