Sinner has missed three Masters tournaments this year, meaning he will be forced to forfeit the £3.3m cash bonus offered to the best player on tour despite being the highest performer, according to Tennis365.

Zverev, meanwhile, is well-placed to land the £1.88m consolation prize for finishing as the runner-up, having reached four semi-finals and one final out of the nine tournaments.

However, he must still perform well at the upcoming Paris Masters, where he will need to better Arthur Fils' result to secure second place.

Zverev was recently beaten in the semi-finals of the Shanghai Masters, losing at the hands of eventual champion Alejandro Davidovich Fokina.

Reflecting on the defeat, the reigning French Open and US Open champion said: "I think if I feel like I could have done something more, then it's painful for me, and it always will be painful. It doesn't change what you won in the past.

"He's playing well, first. Second, I feel like I've actually, in a way, maybe overachieved this week because of how much tennis I played. I carried a little bit of injury, I carried fatigue into the tournament, and I'm okay to lose to a player like this today.

"I think, again, anybody who watched the match maybe saw that I was moving a bit slower. I was maybe not running as much. But again, I'm not going to say anything new.

"I think it's okay. I played a lot of tennis, which is a good sign for me. And I was able to be injury-free this year, which is also a good sign for me."
