In a remarkable turn of events, Serena Williams and her coach Patrick Mouratoglou have disagreed over the decision to impose a coaching violation upon the American during her US Open final defeat earlier this month.

Naomi Osaka defeated Williams 6-2, 6-4 in New York to win her first Grand Slam title, but all the attention was firmly placed on umpire Carlos Ramos’ decision to inflict Williams with a game penalty, following a coaching violation and the docking of a point due to racquet abuse.

While Williams has firmly and consistently denied any allegations that coaching took place during the final, her own coach has remarkably opposed this view, claiming that he was giving her instructions throughout the match.

“I am honest. I was coaching. I don’t think she looked one time.”

Despite admitting that he was helping Williams during the final, he claims that he was not alone and that Sascha Bajin, Osaka’s coach, was equally guilty.

“Sascha was coaching every point too,” Mouratoglou added.

However, Williams is still refuting any accusations of coaching, even following Mouratoglou’s admissions, and is baffled as to why he would make these claims.

“I just don’t understand what (Mouratoglou) was talking about,” Williams told the Sunday Project.

“I asked him, you weren’t coaching, we don’t have signals, we’ve never had signals and he said he made a motion.

“So you said you made a motion, now you told people that you’re coaching me,” she continued. “That doesn’t make any sense, why would you say that?”

While Williams is clearly frustrated over the entire incident, she has claimed that she is trying to move past it.

“What I’m trying to do most of all is to just recover from that.”

Williams will now be hoping that she can put the US Open behind her and get back out onto the court as soon as possible. However, her relationship with her coach will be under scrutiny for a few more weeks to come.
