Jannik Sinner is fully aware of the challenge he faces in his upcoming fourth-round match against Tommy Paul at the U.S. Open. The world number one acknowledged Paul's impressive record on American soil, where the 14th-seeded American has excelled this year, winning the Dallas Open and making it to the final of the Delray Beach Open and the semifinals of Indian Wells.

Sinner praised Paul's game, noting, "He's a great mover. He has improved a lot in the last period of time. It's going to be a tough challenge." Sinner also highlighted Paul's strong performances in the United States, making the match an exciting prospect.

With top rivals Carlos Alcaraz and Novak Djokovic already out of the tournament, Sinner is now the favorite to claim his second Grand Slam title, following his Australian Open victory earlier this year. Sinner attributes his continued success to the partnership between his coaches Darren Cahill and Simone Vagnozzi, who have helped him improve various aspects of his game, particularly his movement, physical conditioning, and serving.

Sinner expressed confidence in his coaching team, saying, "They are two different coaches, completely different, but they work very well together. They have big respect for each other, and this is great to see." As Sinner looks forward to his match against Paul, he remains focused on pushing forward and continuing his strong performance at the tournament.
