Sinner has missed three Masters tournaments this year, meaning he stands to lose the £3.3m bonus awarded to the tour's top performer, despite boasting the strongest overall record.

Zverev, meanwhile, is well-positioned to claim the £1.88m prize for finishing as runner-up, having progressed to four semi-finals and one final across the nine tournaments.

However, he must still deliver a strong showing at the forthcoming Paris Masters, where he will need to surpass Arthur Fils' performance in order to secure second place.

Zverev was recently eliminated at the semi-final stage of the Shanghai Masters, falling to eventual champion Alejandro Davidovich Fokina.

"But if you feel like you've done everything that you could, and I feel like this tournament I, funnily enough, I lost, yes, to Alejandro, who people will say: 'Oh, he's ranked 20 whatever in the world'.

"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."
