Aryna Sabalenka’s coach Anton Dubrov says “clearly something” is amiss with Elena Rybakina as he shared his thoughts on the Kazakh player’s split with her long-term coach Stefano Vukov.

Rybakina has had a troubled 2024 campaign as she has missed several tournaments due to health and injury problems.

To complicate matters further, the 25-year-old also announced before the US Open that she and Vukov have parted company following nearly five successful years together.

The 2022 Wimbledon winner has played only one match since the news broke as she won her first-round match at the season-ending Grand Slam before pulling out of the tournament. She recently also withdrew from the Asian swing, citing a back injury.

Dubrov, who has worked with Sabalenka since 2020, was asked during an interview with Championat if Rybakina’s health issues were “gastrointestinal tract or psychological problems” and he replied: “We communicate well on the courts, but we don’t go too far in personal matters. Injuries, for example, are not discussed. What has been happening in recent months – there’s clearly something. If she wants, she’ll talk about it.

“Maybe motivation or health. When we met at tournaments, she might not feel so good. She would just say: ‘Immune system is low.’” Neither I nor anyone from the team knows. We didn’t write to her personally, because we don’t think it’s quite right.”
