Mouratoglou, who also works with the likes of Stefanos Tsitsipas and Coco Gauff, touched on the Serb’s strict regime that includes having complete control over his body, lauding it as the “perfect example” of how to behave.
“He has spent his whole life making sure that his body is in the best possible shape, going into details that you have no idea about,” the 51-year-old said.
“When you have lunch with Novak once in your life, you know how much he weighs every single element that goes in his plate – the quantity of everything, the quality of everything. That’s incredible.
“He is the perfect example of how you should professionally behave to become the best player in the world. He is obsessed with that.”
