Stefanos Tsitsipas and
Nick Kyrgios developed a rivalry that is up and down in a way as sometimes they seem to get along but other times they fire shots at it.
It started at Wimbledon this year when they played a very heated match and since then we've seen them taking shots at each other multiple times. Kyrgios was actually the player that talked less than Tsitsipas overall with the mother of the Greek getting into it again. He was asked about Kyrgios pulling out of the United Cup only 24 hours before it started and he gave a pretty spicy response.
Tsitsipas said:
"I don't think it's a surprise. I don't see it as a surprise. I hope he enjoys his holidays."
The response indicated that Kyrgios pulled out simply not to play while the official reason was an injury picked up in Dubai. Australia Captain Sam Stosur seemed annoyed when reporters questioned her on it as she explained that she literally found it. Whether there is an injury or isn't, the rivalry continues.
