'Not very smart': Tsitsipas slams his dad after loss

Greek tennis star Stefanos Tsitsipas has unleashed an extraordinary spray at his father and coach, Apostolos, after a shock loss in Montreal.

The world No.11 suffered a surprise 6-4, 6-4 loss to Kei Nishikori in the second round of the ATP Montreal Masters in just 78 minutes.

The senior Tsitsipas has developed a reputation on the tour for heavily badgering his son.

"Masters 1000 matches are important, I need a coach who listens to me as a player," the 25-year-old said after the match.

"My father has not been very smart in handling some situations, in trying to read what is happening on the court.

"It has been a poor performance from my father and it's not the first time. I'm disappointed with him."

Tsitsipas and his father have clashed before, which led to a brief split. In late 2022, he brought Aussie Mark Philippoussis onto his team, but the relationship lasted barely six months before Apostolos returned the following May.

"I really don't know right now if I'd consider any changes, but I'm really disappointed," Tsitsipas continued.

"The most important thing for a player is to have direct and good feedback from a coach. The coach is not the one holding a racket. The player is the one trying to execute a game plan.

"It's a collaborative work that you put in together. It has to be reciprocal in order for me to try to develop my tennis. It's something I don't want to get stuck at that."

Tsitsipas has won only two titles in the past two seasons, and was knocked out of the Olympics singles tournament in the quarter finals by eventual champion Novak Djokovic.

He was bundled out of Wimbledon in the second round.
