Apostolos Tsitsipas

Stefanos Tsitsipas is 26 years old and already a very successful and wealthy tennis player, much wealthier than his parents. But his parents are not just limited to their familial role. They are also his partners and guides in cultivating his talent. It is to be expected that this confusion of roles can cause tensions and psychological complications.

Greek Stefanos Tsitsipas has ended his collaboration with his father Apostolos as his coach, the former world number three said on Friday.

The 25-year-old, currently ranked 11th, had criticised Apostolos' coaching style after losing 6-4 6-4 to former Japanese world number four Kei Nishikori in the second round of the Canadian Open on Thursday.

Greek tennis star Stefanos Tsitsipas has expressed frustration over the coaching approach of his father, Apostolos Tsitsipas, after ejecting him from the stadium during his second-round match against Japan's Kei Nishikori at the Canadian Open on Thursday.
