Jannik Sinner has detailed his biggest weakness following his US Open semi-final win over Jack Draper.

Speaking post-match, Sinner said: “Going for sure on the net, you know, sometimes I miss some volleys. Shot selection sometimes is still, I feel like I can make it a little bit better.

“There are also some small things, the small details that makes a big difference in high level.

“For sure, me and my team, we know what we have to improve. Like, today maybe I should have gone maybe a little bit more on the net sometimes, and all this stuff.

“But, yeah, it takes time, it takes — it’s not like magic, no?”
