“Tough losses are important for my career as they make me want to come back stronger, and without them I feel like I’m perfect: which I’m not," he told the ATP's official website.

“They are crucial for everyone. That semi-final loss was painful, even though it was in three sets.

"I came so close to reaching a Grand Slam final, something I have always dreamed of doing. I also didn’t deliver much in that match, he played well.

"It was a shame, as I’d played well in the two weeks. I went back to the court two days [later] and started to improve."

Tsitsipas finished 2019 in style, winning the ATP Finals in London, but suffered a mid-season lull, which he is attributing to burn-out.

"Burnout is a mixture of a lot of things – stress before and after the match, and trying to reach your goals.

“It’s mostly mental, rather than physical, but it’s about just having a good balance on and off the court. Not so much seeing tennis as a job, more as a game.

"I feel like I took it too seriously at times, I expected too much, demanded too much. The more matches you have, with that mindset, the closer you are to burnout.

"I feel like I need to loosen up sometimes and enjoy the game. I also think I can’t play at 100 per cent every single point.

"I had a pretty spectacular year [in 2019] and the toughest thing will be doing the same this year, through different formulas. I don’t want to duplicate, but I want to do better. I am always aiming for more."
