As a result, the 22-year-old is now at a career-high ranking of World No.15 and Mouratoglou has backed Draper to continue rising.
“I think he’s a great player. Last year when he won Ultimate Tennis Showdown [UTS], I think he played incredible tennis the whole three days,” the former coach of Serena Williams told Sky Sports.
“I feel that now he’s much more mature in terms of his game, his game plan, his game style. Everything looks much more mature. And when you see him win in Vienna, you don’t feel he plays out of his mind. It’s his level. So I think he improved a lot this year.”
The Frenchman added, “I think the big challenge for him now is to stay injury-free because he’s been injured a lot for someone so young. If he manages to stay injury-free then I think he’s definitely a top-10 player and a player that has huge weapons and potentially has no limits.”
