Draper was modelling next summer’s collection for one of his sponsors last week and has been working out regularly at the National Tennis Centre in London this week.

The work is primarily physical at the moment, and when pre-season training begins in earnest later this month, the initial on-court drills are likely to be low in intensity.

The British number one first felt discomfort in his upper left serving arm during the clay court season in the spring, and following a scan after Wimbledon, did not hit any serves for a month.

But the period of rest proved insufficient. He won his first-round match at the US Open, but withdrew before the second, and the opportunity to make his debut at the season ending ATP Finals was gone.

”He’s top 10 and he played half of the year. Just to say how good he is…” Mouratoglou added.

“His only problem for the moment is the injuries: he has been through several injuries already in the past.

“I always thought he was going to be a top player, but for every player that is supposed to become a top player, there are things to solve.

“For him, it’s to find a way to be injury free as much as possible because that’s what made him lose a little bit of time otherwise he would be higher [in the rankings], I think.”
