Moutet suffered defeat in the US Open losing 6-1 6-2 6-7(4) 6-2 to Casper Ruud. However it wasn't his tennis ability that produced questions for the Frenchman.
In the first game of the second set Moutet lost a point when winning 40-30 and his reaction to this was very unexpected. He got down and did 10 push-ups.
The World No.128 then decided to take out his frustration by smashing two balls into the crowd which he then got himself a penalty point for.
Then in the 4th set Corentin Moutet turned his anger towards the umpire where he shouted “Every game, every single game,” and “I’m sweating, I’m playing tennis. I need my towel. Just think. One sec."
His attitude in this game in particular did not come across positively to many well respected ex-professionals.
For example the Eurosport panel gave their opinions after the match,
Barbara Schett said: “[He’s] so difficult to play against. You never know what’s coming up. The way that he behaves on the court as well. The way he plays his tennis. To keep that concentration level high is really a task.”
Alex Corretja continued: “He’s talking a lot to his coach. He’s looking around. And it seems like he doesn’t care that much.
“Some of the things he did today on the court, they were not good for him because he needs just to focus and believe that he can do better than what he did today, in my opinion.”
Mats Wilander proceeded to say “I agree with Alex that his attitude was not good for him. In terms of just tennis, he’s very talented, he plays very smart out there. But to see him from the beginning, not really believing that he has a chance to win."
"I mean he needs to learn from this match. The good thing about Moutet is that he’s such a talented player, he might realise and say, ‘okay I’ve reached the fourth round here, so maybe I’ve a bright future’. He needs to know how to calm down a little bit.” Corretja concluded.
