Stubbs on Ivanisevic, about Rybakina and Vukov: "He won't let this go".
Elena Rybakina and Stefano Vukov are at the heart of the controversy, following the Kazakh's announcement on Vukov's reinstatement to her coaching team.
Vukov is provisionally suspended due to a violation of the WTA code of conduct.
Rennae Stubbs, ex-coach of Serena Williams, believes that Goran Ivanisevic, Rybakina's coach, will not accept this situation.
She says: "It's clear that she's struggling with her relationship with him, whatever it is, and wants him back.
I can tell you right now that Goran is not going to let this go. Absolutely not.
If you want to be in a dysfunctional relationship, that's your problem, but for someone like Goran, he's not going to stay for this."
