His victories at the French Open and Wimbledon in the same season have made him a force to be reckoned with. However, his path to success has not been without its ups and downs. He has had to overcome setbacks and stay focused to maintain his number one ranking.
Even after the Australian Open, where he will defend his title, Sinner remains confident. His ability to perform under pressure and adapt to different playing conditions is truly remarkable.
However, recent weeks have seen a change in their relationship. Anna was not in Turin for the Nitto ATP Finals, and Sinner did not mention her in his speech. Kalinskaya's Instagram posts showed her on vacation in Miami, while Sinner is focused on the Davis Cup Finals in Malaga.
The speculation about the end of their relationship is rife, with Kalinskaya no longer following Sinner on Instagram and liking a post suggesting that he did not take enough care of her. Sinner, however, has chosen to focus solely on tennis for now.
Italy is now the top favorite to win the Davis Cup Finals for the second year in a row. Their performance against Argentina has given them the confidence to go further.
Sinner praised Berrettini's performance, saying that he carried him on the court. Their partnership in doubles has been a key factor in Italy's success.
Captain Lleyton Hewitt has named Kokkinakis and de Minaur in the singles, while Thompson and Ebden will play the decisive doubles. Sinner, despite a long season, still looks fresh and ready to take on the challenge.
Italy could make a different choice in the singles, with Berrettini replacing Musetti. Musetti seemed to struggle against Cerundolo, while Berrettini's skills are better suited to the fast surface.
