As many of you may already know, Osaka has announced she is parting ways with her coach Sacha Bajin. As a long time fan of hers and her rise to being a two-time grand slam champ and current world number one. I can help but feel concerned that the timing of this announcement isn't the best and could impact her motivation and drive in future slams. We have seen champs such as Kerber, impacted negatively following a split from a coach, but eventually bounce back. Personally, I feel the good momentum Naomi had in terms of slams could be brought to a halt. I guess we'll just have to wait for the French Open in a few months time. Keeping in mind that clay has never been her best surface, so its will be interesting to see if she can do well at Wimbledon and defend her US Open title later this year.
