After being humiliated by Ivan, Tsitsipas ended the relationship, with the coach commenting: "Having you coach is not the same as having you evaluate your students."

The partnership between Tsitsipas and Ivanisevic did not last the entire summer. Despite beginning their collaboration after the French Open, where the Greek player was stopped in the second round, Tsitsipas, now ranked 29th in the world, announced on social media this Thursday that his brief collaboration with the Croatian coach has ended.

“My collaboration with Goran, though short, was very intense and a genuinely precious part of my journey. I am grateful for the time, effort, and energy he dedicated to me and my team. Now we are each on different paths, and I hold great respect for Goran, not only for his achievements in tennis but also for his qualities as a person. I sincerely wish him all the best in the future.”

Under Ivanisevic's guidance, Tsitsipas achieved only one victory — in the first round of the Halle grass court tournament. He then lost in the second round to Michaelson and had to retire due to injury in the first round against French player Valentin Royer at Wimbledon.

After Wimbledon, Ivanisevic strongly criticized Tsitsipas's physical condition in an interview with CLAY, making the split not surprising. "His physical condition is a disaster. I don't understand how a player at this level can be in such poor shape. He says he desires success but does nothing. I was shocked because I have never seen a player so poorly prepared. Even with a knee injury, my physical state is three times better than his," he stated.

Mouratoglou, the current coach of four-time Grand Slam champion Naomi Osaka and former coach of 23-time Grand Slam winner Serena Williams, recently stated that he disagrees with Ivanisevic's method of publicly criticizing players.

“To be honest, this (Ivanisevic's approach) is completely not the coaching style I advocate. He made some comments about Tsitsipas that were unnecessary to repeat to 'feed the trolls.' Simply put, he implied that Stefanos is worthless and needs to change everything. If Goran accepted this job, he must have known that Stefanos's approach had issues or needed changes,” Mouratoglou wrote in a post.

“This is a tough time for Stefanos. He is not performing as he used to. But the fact is: when I took over Serena or Naomi, they were also in a low period. Goran also knows that Stefanos is going through a difficult stage. Blaming someone does not help. Most importantly — this is not what a coach should do.”

Mouratoglou has a close relationship with Tsitsipas, as the Greek player has been training at his tennis academy in France for a long time. He added that Ivanisevic seems to be deliberately distancing himself from the player's poor performance, which is not the behavior of a good coach.

“Coaching is not about judgment, absolutely not. On the contrary, it is a process of understanding player behavior and helping them through companionship and solidarity. Judgment is not a healthy way to operate, and making that judgment public is even worse. It makes me feel like Goran is ashamed of the results and wants to distance himself from Stefanos. It's like saying: ‘It's not me; it's his problem. I have no issues; he does.’”

“This is not coaching; strictly speaking, it is the opposite of coaching. You can certainly talk about your players in public, but you shouldn’t throw them to the wolves. Most matters should be handled behind the scenes. It’s a one-on-one relationship — it needs to be built. I don’t know the internal details, but I find it hard to believe they can cooperate smoothly anymore. A coaching relationship requires trust, and this is not the way to build trust.”

Mouratoglou agrees that Tsitsipas is currently in a difficult phase of his career, but he disagrees with Ivanisevic's assessment that "he is worthless."

“Is everything Stefanos does right? Maybe not. But is he worthless? Absolutely not. No one is worthless. He has been a professional player for many years and knows how the tennis world operates. He is just going through a tough phase. And tough times can lead to mistakes. As a coach, your job is to get him back on track. You have to do it together; there is no other way.”(Source: Tennis Home, Author: Spark)
