believes his former coach Goran Ivanisevic can rebuild Stefanos Tsitsipas' self-belief. It was announced this week that Ivanisevic, who enjoyed enormous success during a five-year working relationship with Djokovic, has linked up with Tsitsipas.

A change of coach follows the Greek star's disappointing second-round French Open exit. Beaten by world No. 167 and qualifier Matteo Gigante, a tough year grew even more disappointing for the 26-year-old. Tsitsipas has now made a change to his coaching team, bringing in the 10-time Grand Slam-winning trainer Ivanisevic. Djokovic, with whom the Croatian won nine of those major titles, believes the move could be good for Tsitsipas, who the Serb says "visibly" lacks belief in his own game.

"I'm sure he can help any player, and especially Stefanos, mentally. I can see that Stefanos has bigger fluctuations in that regard now. He doubts his game, it's visible. I believe Goran can guide him a bit and draw his attention to the right things," Djokovic said.

"When we talk about Goran Ivanisevic, the serve is number one. Stefanos has a good serve, but there's always an element that can be improved. And the backhand - we all know that's probably the weakest point of his game. Even though Goran played with a two-handed backhand, I'm sure he has a clear vision of what he wants to do with him. It will be interesting to see how their cooperation develops."

Tsitsipas confirmed the news on his Instagram account yesterday. He has moved on from Kerei Abakar and Dimitris Chatzinikolaou to work alongside Ivanisevic.

"I'm happy to begin a new chapter with Goran Ivanisevic joining my team as coach," the world No. 18 said. "Goran's experience, passion for the sport, and champion's mindset are things I greatly respect, and I'm looking forward to the journey ahead with him by my side. I'm optimistic about what we can build together.

"I would like to express my heartfelt gratitude to Kerei and Dimitris for their dedication, support, and work over the past few months. Working with them has been a meaningful chapter in my journey, and I'm deeply thankful for the effort and commitment they brought to the team."

Tsitsipas will hope to have a vastly improved summer under Ivanisevic. He was also beaten in the first round of the Australian Open and suffered third-round exits in both the Madrid Open and the Italian Open.
