Stefanos Tsitsipas had lost to Roger Federer a few weeks ago in Basel, and the Greek avenged his loss to the Swiss at the ATP Finals in London. The Greek said: "I did manage to play this way in Basel when I faced him. I was kind of disappointed and left from that match knowing that I haven't really gave out in the court my best.
I still had plenty of things to do better. So for me was a good start, a good way to take things for the next upcoming match against him. I think I learned a lot of things from my Basel match against him. He did play well there, but, you know, once you get the patterns, once you analyze a bit the game better and know what to expect next time, you always feel and you always want to put yourself in the state of mind where you think that you can always do better."
On having a huge Greek fanbase in London, Tsitsipas added: "It's very important, although today I did feel like more Swiss fans than Greek fans. Yeah, I tried not to be bothered by this, because I did receive a lot of fan support until this match today, and I did hear people yell my name and supporting me in Greek.
It's important. It's important for the growth of the sport in our country. I enjoy having people from Greece come support me, and I hope they do more often because that makes me feel closer to playing home, let's say. Gives me a tremendous amount of energy."
