Sinner: "I'm currently playing at a very high level".

Qualified for the final of the ATP Finals, Sinner is in excellent form. After his impressive victory over Casper Ruud (6-1, 6-2), the Italian commented on his current level of play: "It's been an excellent year.

My good preparation and intelligent organization of the calendar were crucial. The balance sheet is more than positive, but there's still the Davis Cup to come.

Against Fritz, I know it will be difficult to win. He's really raised his game, and in our group stage match, it all came down to small details.

Finals are always special matches. I have to pay close attention. In any case, I feel I've made a lot of progress as a tennis player over the last twelve months.

Right now, I'm playing at a very high level. I'd be lying if I said I wasn't surprised by myself. I don't consider that normal, and I can assure you that I'll never take anything for granted."
