The Greek lad, Stefanos Tsitsipas became the youngest champion of the season finale since 2001 after Boris Becker. The debutant in London, Tsitsipas was on cloud nine after his taxing win against Dominic Thiem and in the midst of the celebrations, the Greek became tipsy.
He celebrated with his team which included his coach, Patrick Mouratoglou, father and coach, Apostolos Tsitsipas, mother and a few others.
In London, Stefanos Tsitsipas lost a match to World Number one, Rafael Nadal in tough three sets and besides that, until the final, the Greek star eliminated the elite ATP men in straight sets.
With a win over the 20-time Grand Slam, Roger Federer he earned his first Grand Slam semifinal ticket earlier this year in Melbourne. “I feel like my game is getting better over time,” he said after his career’s biggest title win in London. “I believe I’m really close to being crowned a Grand Slam champion. I know these are strong words that I say, but I do feel like I belong to be there.”
Last year, Tsitsipas was a champion at NextGen ATP Finals in Milan and within a span of 12 months, he reached a Slam semi-final, pulled off victories against the ‘Big Three’ on eminent tennis courts, touched the career-high ranking of World Number six, won a few ATP titles and curtained down his season with the ATP World Tour Finals 2019 crown.
“[I want to] refresh and come to enter into 2019 stronger and better, just a better Stefanos than 2018. I came with a lot of confidence in the  Next Gen ATP Finals knowing I’m one of the best and I can do really well. Left with the trophy. Felt unbelievably excited for the new season because I beat the youngest generation of players. I think that gave me a tremendous amount of boost,” Tsitsipas said.
“He is box office,” Boris Becker said after Tsitsipas’ triumph in London. “We always ask the question of where is the road going after Federer, Nadal, and Djokovic. After this week, I think tennis is in safe hands.”
