But Vukov refused to sit silently - and after appealing the WTA's ban - he won his case and rejoined Rybakina's team at the Cincinnati Open. And that is already having a positive impact on the Kazakh, who is through to the semifinal after ousting top seed Aryna Sabalenka 6-1 6-4.

Chakvetadze, a former world No. 8, appeared on a podcast with former three-time Grand Slam finalist Safina. At one point during their conversation, the former Russian tennis star said that Ivanisevic privately told her he was surprised that Rybakina only had one Wimbledon title in her collection.

The coach of 2022 Wimbledon champion Elena Rybakina has been cleared by the WTA Tour to return from his suspension for a potential breach of its code of conduct.

The Cincinnati Open is starting to heat up on the tour. With the quarterfinal matches on the cards, players will be hoping to enter the final four this week.
