Coach Patrick Mouratoglou believes Serena Williams' infamous on-court row with umpire Carlos Ramos during the 2018 US Open final was "great for tennis".
Williams lost the final against Naomi Osaka in straight sets, with the Japanese youngster claiming her maiden Grand Slam title at New York's Arthur Ashe Stadium.
But the final is remembered for the American's outburst, after Williams received a code violation for being coached from the stands by Mouratoglou.
Williams became agitated and eventually received three code violations, including a game penalty for verbal abuse, calling Ramos a "thief" and accusing him of being "sexist".
Williams continually protested her innocence, but Mouratoglou later admitted his guilt.
"Of course, it is not very comfortable when you are in the eye of the storm, but I am not scared, I am very relaxed," Mouratoglou is quoted in the Daily Mail.
"I didn't do anything wrong, I just did what all coaches do all year long.
"I think [Ramos] did a terrible job, but we all make mistakes. Coaches coach, we all know that, but it was the best day for tennis, because tennis is everywhere.
"It's great for tennis, so it depends on how you look at it."
Mouratoglou admits the Williams camp was tense afterwards, but insists it was good for the sport, claiming that tennis is "in trouble".
"People watch sports like they watch a movie - they want to feel emotion," he added.
"Watching tennis today is like watching a movie full of very nice people doing nothing wrong. We lack a bit of authenticity.
"I love tennis, but I think it is in trouble and I've known that for a long time. The fans we have are usually those that fell in love with the game in the '70s or '80s, and we are living too much on that fan base.
"I don't think the personalities were better then than they are now, but people were expressing themselves more.
"Players don't dare be themselves. They feel they will be judged and they will lose their contracts."
With the tennis season currently suspended until the start of August, Mouratoglou is launching his own competition, known as the Ultimate Tennis Showdown, which is due to start next week.
Over the next few weeks, his academy in the south of France will host matches among some of the game's best up-and-coming stars, including with world No.6 Stefanos Tsitsipas.
