Patrick Mouratoglou has sprang to the defence of Stefanos Tsitsipas, accusing a popular tennis website of 'bullying' him.
Tsitsipas came in for a lot of criticism at the US Open, with players and media suggesting he was abusing the comfort break rule to earn an unfair advantage during matches.
The criticism has not been universal, but the more high-profile names such as Andy Murray, Alexander Zverev, and Toni Nadal have tended to come down on the side of criticising the Greek.
Mouratoglou, though, who is part of Tsitsipas' coaching team, has come out fighting in defending his player on social media.
Mouratoglou took exception to a Tweet from We Are Tennis, who made a joke about Tsitsipas' well-documented comfort breaks.
"Not pretty to hit a man when he is down," Mouratoglou tweeted in response. "Always feels safer to rally the pack though."
One response to Mouratoglou's tweet described the criticism of Tsitsipas as 'borderline bullying' and the Frenchman agreed.
"Thank you for bringing that up," he said. "Interesting to note that the world is very much rightly into mental health and the same people who advocate for it would bully the players."
