During the recent match at the Ultimate Tennis Showdown, Corentin Moutet was leading already 2-0 on quarters against Stefanos Tsitsipas. But things started to slip out of his hands quickly as he started to argue with the father of Stefanos, Apostolos Tsitsipas, and later also with the chair umpire.

It started in the 4th quarter when Tsitsipas was leading 10-5. Moutet started to complain about the fact that Tsitsipas' father was talking during the Frenchman was serving. Stefanos also joined the argument when he said that he 'doesn't care'. Moutet replied: "Of course you don't care, it's your father."

During the interview between the quarters, Moutet was asked about the argument again. The Frenchman again said that Apostolos disturbs him and added: “It’s not respectful. Nothing against Stefanos, he’s a great guy. It’s just his father. He’s stupid.”
