By doing so, he joined the likes of Novak Djokovic, Michael Chang, and Rafael Nadal as players who have won the prestigious ATP 500 title multiple times.Since Djokovic has the most China Open wins, Sinner was asked whether he has a goal of matching the legendary Serb's feat. In response, the latter refused to be compared with Djokovic and said:"I always say comparing me to Novak, he's in a different league with everything he has achieved in his career. I'm just a normal 24-year-old who tries to play the best tennis possible. I know I've won some great titles in my young career, but let's see how long I can hold it. What Novak, Rafa and Roger did for 15-plus years was amazing. Novak is still here and showing some incredible tennis. So let's see," he said in the post-match press conference. Jannik Sinner won four major titles and first achieved the No. 1 rank when he won his first Grand Slam at the Australian Open, followed by three Masters events, the US Open, and the ATP Finals in 2024. He was the first Italian tennis player to reach the top ranking.
