"Just say it was your team's fault": Nick Kyrgios targets Jannik Sinner’s doping scandal in response to Muller
ATP
Nick Kyrgios responds to Alexandre Müller over doping test comments, taking the chance to throw another jab at Jannik Sinner. The Australian never misses an opportunity to criticize the world No. 1, especially after Sinner agreed to a three-month suspension with the WADA.
Sinner will be off the courts until May 2025, with a possible return at the Rome Open, his home event. A few weeks later, he will play the French Open, meaning he won’t miss any Grand Slam tournaments due to the suspension.

Meanwhile, Alexander Muller, who competed this week at the Rio Open, criticized the late-night doping tests, mentioning how he had to wait to take his test. The Frenchman defeated 8th seed Tomas Martin Etcheverry in the Round of 16 on Thursday and will face 4th seed Francisco Cerundolo in the quarter-finals on Friday.
“Doping test when we finish at midnight... come on... ATP Tour,” posted Alexandre Muller on X, receiving a reply from Kyrgios, who took the opportunity to send another jab at Sinner.
“Just say you ‘don’t know’ and that it was completely your team’s fault if there are steroids in there 😂,” Kyrgios posted, referencing the world No. 1's case.

The ITIA ruled that Sinner was not guilty of ‘negligence or fault’ after the 3-time Grand Slam champion claimed the error was due to his physiotherapist using a product containing Clostebol to treat wounds on his own hands. After treating Sinner without gloves, the product may have contaminated him with a tiny amount of the substance.

The WADA had announced an appeal, seeking a suspension of one to two years, with a hearing scheduled for the end of April. However, they decided to withdraw the appeal and reached an agreement with Sinner for a three-month suspension starting February 9.
With the three months off, Sinner doesn’t defend “too many points,” losing 1,800 points, which doesn’t affect his standing as world No. 1 upon his return.

- Either Lena has a chronic internal ailment (i.e., colitis, enteritis, Crohn's, or some type of lower abdomen issue) -- or she is once again dealing with 'Vukovitis'. Mental stress can indeed cause lower body pains. No matter... whatever is truly going on sucks. "Virus" excuse is getting a bit old -- and often -- at this point.
mandoist09-11-2026 - Ironically, Martina became a U.S. Citizen about the same time as the Orange Convicted Felon & Abuser was just beginning on his road to losing all Daddy's Millions!!
mandoist09-11-2026 - "Another fresh start is in the cards." Thanks for the Humor!! I'm guessing this is the minimum one can do to keep all your sponsors hanging-on in perpetuity?
mandoist09-11-2026 - Vukov is doing this to Lena... AGAIN!!!!! WTA's autonomous collective should be dismantled for allowing Vukov to re-emerge from his hand-slapping suspension. Just ask WTA employees how that's been going lately as they witness his continued verbal abuses. Women's Pro Tennis should start over.
mandoist08-11-2026 - Can't help but suspect Vukov is back to his old self again. Thank you, WTA. Perhaps you can give them a "Battling Couple of the Year Award 2026" ??
mandoist08-11-2026 - Wtf? Why is there no reason? And what about the men's?Bel08-11-2026
- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.
mandoist06-11-2026 - Enough of her bullshit. Go marry someone.
mandoist06-11-2026 - Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
