Jannik Sinner has not tasted defeat on the ATP Tour since February.
After his quarterfinal exit at the Qatar Open, the Italian won four straight titles, all of which came at ATP Masters 1000 tournaments.
Sinner emerged victorious in Indian Wells, Miami, Monte-Carlo and Madrid, with the world number one clinching the record for the most consecutive Masters crowns won in history.
Can any of these four players stop Jannik Sinner winning the French Open this year?
Is there anyone else you think could be a threat to Sinner?
On Saturday, he kicked off his Italian Open campaign with another straight sets victory over Sebastian Ofner.
Though he looks simply unstoppable at the moment, Sinner admitted he still questions his game sometimes.
Jannik Sinner speaks after his opening win in Rome
Asked in his post-match press conference if he still has doubts at this point in his career, Sinner gave an honest response.
He said: “Before every match, I have doubts. It’s the most normal thing, and if you don’t feel the doubt, if you don’t feel the pressure, it means you don’t care, right?
“I’m more aware than many years ago, but at the same time, even today I go on the court, and I have my little doubts about what if this or that were to happen, but you have to manage it.
How long will Jannik Sinner stay as world number one?
Sinner will begin his third reign after winning the Monte Carlo Masters…
“In my opinion, doubt is connected a little bit with the pressure itself. I think each of us has doubts; it’s the most normal thing.
“You also have to be aware that you know how to do certain things, and then you have to go.”
Jannik Sinner’s next opponent at the Italian Open
Sinner’s next assignment at the Italian Open comes in the form of Alexei Popyrin, a former ATP Masters 1000 champion.
Popyrin, who hoisted the 2024 Canadian Open title, recently ended a long dry spell in Rome by clinching his first win at a Masters event since the Cincinnati Open in 2025.
The Australian star beat Matteo Berrettini in the opening round and followed it up by knocking out 26th seed Jakub Mensik.
Sinner and Popyrin have played three times before on the ATP Tour, with the four-time major champion leading 2-1 in the head-to-head.
Popyrin sealed the first win at the Madrid Open back in 2021, but Sinner has since defeated him at the 2025 US Open and the 2026 Qatar Open.
