Sinner on his confidence: "I have already experienced great moments in my career for my young age"

Jannik Sinner has qualified for the quarterfinals of the ATP 500 in Vienna. The Italian will face Alexander Bublik this Friday.

After his victory against Flavio Cobolli, a journalist asked him if he was at the peak of his confidence. He replied: "I don't know. For my age and my youth, the truth is that I have already experienced great 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 here. I try to play the best tennis possible, accepting the difficult days with pleasure.

Today, I can only go to bed happy after my performance, so let's hope everything goes just as well tomorrow."
