As reported by Spanish magazine Hola!, the Greek and the Spaniard have once again decided to go their separate ways. This time around, tensions between the couple first surfaced in the aftermath of their disappointing Wimbledon campaigns, with Tsitsipas and Badosa unfollowing each other on social media.On the tennis front, the former ATP No. 3 and two-time Grand Slam finalist decided to make a major change to his coaching setup.Stefanos Tsitsipas chooses to move on from Goran Ivanisevic in the aftermath of coach's fierce criticismStefanos Tsitsipas (left) and Goran Ivanisevic (right) during a practice session at the 2025 Wimbledon Championships (Source: Getty)A back injury put Tsitsipas' campaign at this year's Wimbledon Championships to the sword in the first round. Trailing qualifier Valentin Royer by two sets, the Greek decided to retire mid-match. To add insult to injury, days after the 12-time career singles titlist's disappointment at SW19, coach Goran Ivanisevic blatantly criticized the Greek. Ivanisevic began coaching Tsitsipas after the 2025 French Open."The desire is there, but he does nothing to improve things. At least I can not notice his effort. Stefanos has to find a solution for his troubled back. I have never seen a more unprepared player in my life! At my age and with the state of my knee, I'm in thrice better shape than him. I'm not sure what he has done in the previous 12 months, but his current shape is very poor," Ivanisevic told Sport Klub.Later, in a separate interview, the Croatian former ATP icon and present-day coach admitted that his comments had rattled Tsitsipas. On Wednesday, July 23, the Greek announced via Instagram Stories that he would no longer be working with Ivanisevic.
