Another day at the office for Jannik Sinner at an ATP 500 in Vienna where no one seems ready to stop him. After defeating Flavio Cobolli on Thursday, the Italian will now face Alexander Bublik in the quarterfinals.

The match started without much to tell, it took the second set for Flavio Cobolli to step up a gear and show what a good competitor he is. Today the challenge was huge, facing Jannik Sinner for the first time, and in a tournament like the ATP Vienna 2025, with conditions tremendously favorable to the world's No. 2. In the end, he lived up to it, but we had to wait a few games for the match to live up to the expectations. Sinner now has 17 wins against players from his country, keeping his unbeaten record in this regard.

"Flavio is a player who is having a spectacular season, I see him improving week by week, so I approached this match fully aware of what he is capable of," San Candido's player said to TennisTV. "He is one of the great talents we have in our tennis, although we had never faced each other before. He has a lot of quality in his shots, as well as being a great competitor. Today I think we both showed a good level on the court, he had many more opportunities in the second set, where I tried to stay solid and focus solely on the present, never losing my aggressive style and appropriate mindset. I wish Flavio the best for the end of the season," he added affectionately.

Jannik Sinner, a man who never relaxes

Some were impressed by his assertive way of defeating Daniel Altmaier in the previous round, just as they must have thought when they saw the first set tonight against Cobolli. The thing is that this way of dominating, that thirst for always seeking your best version, is something Sinner saw throughout his career in Rafa Nadal. Let's say this is one of the many legacies that the Spaniard left on the circuit even long before retiring. That's why Jannik is such a good competitor, because he doesn't understand rounds or opponents; he always goes out there to give his best.

So when the journalist asked if he is currently experiencing his most confident moment, Sinner couldn't answer, thinking of an endless list of moments where he already felt that energy inside him. "I don't know, for my age and still being very young, it is true that I have already experienced very big moments in my career. I think a lot about every match I play, I never take anything for granted. I am very happy to be competing here, trying to develop the best level of tennis I can, accepting with grace the tough days that may come. Today, I can only go to bed happy after the performance I had, so let's hope that tomorrow things work out equally well," said the man who will face Alexander Bublik in the quarterfinals tomorrow.
