Elena Rybakina's partnership with Goran Ivanisevic has concluded just one day after her fourth-round exit from the Australian Open.
The former coach of Novak Djokovic stepped in for the first grand slam of the year after Rybakina's coach Stefano Vukov was provisionally suspended earlier this month.
However, things did not work out, with the world No.7 eliminated on Monday afternoon, falling in three sets 6-3, 1-6, 6-3 to American star Madison Keys.

In a statement posted to his Instagram account, Ivanisevic confirmed the pair had gone their separate ways.
"After our trial period that finished with [the] Australian Open, I wish Elena and her team [the] best of luck moving forward," he wrote.
Rybakina travelled to the tournament in Melbourne with plenty of headlines surrounding her and sidelined coach Vukov.
Before the major kicked off, WTA officials provisionally suspended Vukov over code of conduct breaches, banning him from being inside Melbourne Park.

He was replaced in Rybakina's corner by Ivanisevic and while the sudden change was not used as an excuse for the Kazakhstani's performance against Keys, the sixth seed admitted it did take a toll on her campaign.
"Definitely – as I said before, this is not the position I want to be or someone wants to be in," Rybakina said during her post-match press conference on Monday.

"Of course, I want to have who I want in the box, but I couldn't change it.
"At the end of the day, I just tried to focus on my matches, and I spoke with him. I also have Goran, so it didn't affect the way I played today or the result."
At this stage, it remains unclear how long Vukov will be barred, with investigations into his conduct as a coach still ongoing.
Asked whether she would keep Ivanisevic on her staff, Rybakina had reservations.

"Well, we still need to talk," she said.
"We just tried [working together] in the pre-season and these couple of tournaments it was something just getting used to each other.
"We will definitely talk [about] how the next schedule is going to look like."
On top of her coaching dramas, Rybakina also dealt with a back issue at the Australian Open, conceding she "still had some pain" after battling it out with Keys.
