Nick Kyrgios criticizes Jannik Sinner amid doping controversy

Nick Kyrgios has publicly shifted his stance on Jannik Sinner, who was previously referred to as his 'favorite player' before being embroiled in a doping controversy. Sinner tested positive for the banned substance Clostebol, but after an investigation, he was cleared of wrongdoing, a decision that Kyrgios has vehemently criticized. The Australian tennis star has repeatedly attacked Sinner on social media, asserting that he should face a two-year ban following the positive test. Despite the tension, Sinner has chosen to remain silent on Kyrgios's remarks, emphasizing that he knows the truth of the situation and does not wish to engage in public disputes. Sinner is scheduled to appear before the Court of Arbitration for Sport in April regarding the doping case, which could still result in a suspension. Kyrgios's ongoing criticisms and jabs at Sinner suggest a personal vendetta, despite his claims that it is not personal.
