In February 2013, Horacio Zeballos claimed the only ATP title in singles in Vina del Mar following that epic victory over Rafael Nadal in the final. The Argentine became the top-40 player soon after that, reaching his peak in singles and never repeating that level in the years to come.
The Mar Del Plata has experienced the "second youth" on the doubles court in the last couple of years, becoming world no. 3 and lifting Masters 1000 trophies alongside the final at the US Open. Waiting for the season to resume like all the other players, Horacio joined a podcast and spoke about various topics, mentioning the players from the top and sharing his thoughts who is the best among them.
For Zeballos, Novak Djokovic is the better and more complete player than Roger Federer and Rafael Nadal, praising the Serb's abilities and seeing him as the future GOAT after breaking Roger Federer's record for the most Major titles.
Horacio and Novak played two times and the Serb grabbed two wins in straight sets, taking down the Argentine 6-3, 6-4 in Doha 2017 without facing a break point and a year later at Wimbledon where Novak sprints towards the finish line with a 6-1, 6-2, 6-3 triumph in 91 minutes.
"With no doubt, Novak Djokovic is the most complete player out there, ahead of Roger Federer and Rafael Nadal. It is tough to play against him, especially when you serve as he has an incredible response on the return, sending the ball back with ease.
I believe that, in my best days, I could have given Roger a fight; the same goes for Nadal who sometimes struggles on surfaces he doesn't like. Novak Djokovic is the hardest rival out there; I think he will break Roger Federer's Majors record."
