There is still room for improvement," says Sinner about his game

This Sunday, Jannik Sinner won the ATP Finals against Carlos Alcaraz. The Italian had a perfect week, winning all 5 of his matches without conceding a single set. When asked about the aspects of his game that have improved, he responded.

"They have of course evolved positively, particularly the serve. From the baseline, it was a bit more unpredictable. It worked well, or at least better. However, I think there is still room for improvement.

It's also difficult because you have to pay tribute to your opponent. Carlos is an incredible player. He has enormous talent. It's tough. You have to win every point in a very fair way. You have to push your limits.

But yes, I think the work we have done has been very positive. Of course, otherwise, you don't get these results. As I always say, the month of December is very important for me as a player and as a team, because we connect better, because we don't have the pressure of a tournament, the rush of going from one place to another.

It's very important not only for the work ethic, but also to connect the entire team even better and understand each other even more.
