Rybakina split with Goran Ivanisevic after the Australian Open, having only just hired him ahead of the 2025 season.
Another coach in Stefano Vukov meanwhile was not allowed to accompany Rybakina in Melbourne after being provisionally suspended by the WTA for a potential breach of conduct.
That suspension has since been made official, with Rybakina making another change in Abu Dhabi last month with the addition of Davide Sanguinetti.
Rybakina reached the semi-finals in Abu Dhabi, in what was her first tournament since she fell in the fourth round of the Australian Open.
She lost to eventual champions Madison Keys and Belinda Bencic respectively, before falling to Iga Swiatek in the quarter-finals of the Qatar Open.
The 2022 Wimbledon champion then lost to another eventual champion at the Dubai Tennis Championships, with Mirra Andreeva winning their semi-final match.
And she now has yet another coaching change to deal with, with fitness trainer Azuz Simcich confirming his departure, having worked with Rybakina since the end of 2022.
