Jannik Sinner to return from doping ban at Italian Open in Rome

Sinner was surrounded by his trusted team in Monaco – coaches Simone Vagnozzi and Darren Cahill, plus fitness trainer Marco Panichi, physio Ulises Badio and osteopath Andrea Cipolla.

Draper said the trip was strictly business.

“I didn’t speak to him too much to be honest,” added the 23-year-old world number six, who lost to Sinner in last year’s US Open semi-finals.

“On the court, Jannik is always very professional – he’s number one for a reason.

“He seemed in good spirits, had a great team around him and great people who have supported him through a tough time.”

Once Draper moved on to the Madrid Open, Sinner enlisted the help of Norwegian teenager Nicolai Budkov Kjaer in practice sessions.

Off the court, Sinner has spent time with his family back in Italy and has pursued his other interests outside tennis.

Shortly after the announcement of his ban, he was pictured sitting alongside Vogue editor Anna Wintour at Milan Fashion Week.

According to a source close to Sinner, the player has been enjoying skiing, biking and go-karting between tennis sessions in recent weeks.

“I think he is feeling refreshed – tennis is very relentless. I’m sure he will come back to Rome and the rest of the year in fine form,” said Draper.
