Stefanos Tsitsipas' coach Patrick Mouratoglou praised the Greek player for his ATP Finals title in London. The Frenchman believes the 21-year-old delivered a huge level throughout the week. "He played better than his opponents in all matches, only probably Rafa was better than him (in their match).
Mental strength is one of his best qualities, most of the people don't believe as much as he does. He does have very high expectations. When he lost in the Australian Open semifinals to Rafa, he was destroyed despite he had beaten Roger Federer.
This is not something you cannot teach. He still has a lot to improve, we just have to stay focused and that's the most important thing. His improvements over the last two years have been amazing. We have to get ready very soon for the next year."
Apostolos said: "Having a break doesn't mean anything. Having the match point maybe means something. I said before the match it was a mental match and he was there mentally. He made a difference in the key moments. He has been making an improvement and the ATP Tour provided an amazing job organizing the Next Gen Finals and giving the chance to the younger players to play it.
Congratulations, it's amazing what you do. If the player really believes in himself and does his job well, it works", said Apostolos referring to Tsitsipas winning the sub-21 age event in Milan 12 months ago. Marcos Baghdatis said: "Stefanos was more consistent than Thiem, both of them played aggressive tennis but Thiem made more unforced errors than his opponent."
