And he becomes the just the second player this century win the event in his debut after Grigor Dimitrov two years ago. "And now I'm in the position to be champion, so it feels awesome".
Djokovic was also the last ATP Finals champion to go on to win a major title.
"That is unbelievable", Tsitsipas said when reminded of that day. Dominic Thiem, at 26, is by no means from the sprightly NextGen but his confident performances in opposition to the game's best on his minimum preferable indoor hardcourts communicate volumes of his intent in bridging the hole with the Massive 3. "He is very attractive to watch, I love to watch him and I am looking forward to playing him again". It's unbelievable, isn't it?
Nadal's princely haul includes an unprecedented 12 French Open crowns, as well as four successes at the US Open, including his 2019 triumph when he toppled Daniil Medvedev in a breathtaking final.
It was quite a final, too.
Stefanos Tsitsipas overcame Dominic Thiem in an epic final of the 2019 ATP Finals in a third set tie break.
World No.6 Tsitsipas and world No.5 Thiem saved two and three break points, respectively, in the first set and held their serves till 6-6 to head into the tie-breaker. "But I can not do anything now about it". We had some really good matches.
But Tsitsipas, who has beaten every member of the "Big Three" in 2019, will go into the new season with the belief he can take the next step towards the apex of the men's game.
Tsitsipas, who a year ago won the next-generation ATP Finals, a tournament that ends the season for the best players age 21 and under, impressed with his composure and fearless attitude in the debut to provide further confirmation of his growing reputation.
The Greek has already grown quite the fan base, partly because of a Bjorn Borg-style haircut and partly because of an aggressive playing style that is a bit old-school with frequent forays to the net. "We put on a great show". It's great that he's up on the top and he's going to fight for the big titles in the future. I'm 100% sure of that. "I would like to thank everyone who supported me with a Greek flags and made me feel at home".
"I think if you play it well like we do, it has a lot of advantages, and also or maybe especially indoors because of the slice, because of the many options you have".
"I believe that if Rafael wouldn't have had so many injuries, probably today he would be the best tennis player in history".
"From that point of view, it's a very disappointing loss, very hard to digest". "But on the same hand, I had some incredible wins also".
Zverev demolished Nadal to reach the semi-finals in London, but was disappointing in a straight-sets defeat against Thiem.
