Nick Kyrgios and
Stefanos Tsitsipas played a doubles match together recently and they weren't that excited by it showing some cold body language during it.
They lost the match but it was fairly close with two tiebreaks deciding it. Kyrgios and Tsitsipas both commented on the match before it but weren't so excited by it during it. Both showed a rather cold persona during the match barely interacting besides what was needed to effectively play the match.
After the match, Kyrgios referred to the situation by posting a picture of them when they were younger and far more accepting of each other than now. They played a very heated clash at Wimbledon with both having some strong words for each other after that match. Check out the photos below.
