Furlan, Paolini's coach, on Sinner: "Before his semi-final in Cincinnati, he was heard by the authorities from 4 a.m. to 10 a.m."

Renzo Furlan, coach of world No. 4 Jasmine Paolini, revealed on Italian television how Jannik Sinner handled the pressure surrounding his doping case at the Cincinnati Masters 1000.

For example, the world No. 1 had to report to the anti-doping authorities just hours before his semi-final against Alexander Zverev (which he won 7-6, 5-7, 7-6):

"There was always this doping situation hanging over his head. I said to him: 'You've managed to do extraordinary things even under this pressure.

And he replied: 'You know how it went in Cincinnati? Things could have gone well or badly.

For the first time, we rented a house instead of a hotel room. We had two cars to transport us.

I drove one and my team drove the other. I needed these moments to myself. It's something that may sound silly, but it gave me great peace of mind.'

It's worth remembering that this guy, before the semi-final against Zverev, had to be heard from 4am to 10am.

He was then acquitted and, in the afternoon, won his match in three sets. Only someone with extraordinary qualities can do that."
