Jannik Sinner hits back at Nick Kyrgios after he slams Wimbledon champion over doping ban

Wimbledon champion Jannik Sinner has responded after Nick Kyrgios made his feelings clear on his triumph after serving a doping ban.

The 23-year-old, the No.1 ranked tennis player in the world, won his first Wimbledon title on Sunday - defeating Carlos Alcaraz 4-6, 6-4, 6-4, 6-4 on Centre Court to deny the Spaniard a third consecutive triumph.

The Italian claimed his fourth Grand Slam title after winning the Australian Open twice as well as the US Open.

His win comes just two months after Sinner returned from a three-month doping suspension after a positive test for the banned anabolic steroid clostebol.

Sinner, who failed two doping tests, gave the explanation that the clostebol had been passed onto his body following massages from his physiotherapist, who used a treatment containing clostebol to treat an injury he suffered himself.

Iga Swiatek, winner of the Ladies' Wimbledon final, also tested positive for a banned substance in an out of competition sample - with trimetazidine - which can improve brood flow and improve endurance - in the sleep medication melatonin she was taking.

Swiatek was hit with a one-month suspension in November and Kyrgios, the 2022 Wimbledon finalist, weighed in with his thoughts ahead of both finals.

"At the end of the day, the decision has been made, and it's kind of in the past," Kyrgios told The i Paper.

"Do I think it's a good look for the sport that [Iga] Swiatek and Sinner are in the final at Wimbledon after serving a ban? I don't think it's a good look for the sport. And I think people could agree."

The Australian, who worked as a pundit for Wimbledon due to a wrist injury he is suffering from, also posted a cryptic response to the result as he tweeted an asterisk - in what appeared to be a suggestion that the victories were tainted.

He then reposted another comment on social media, where a user had written, "Congratulations to Clostebol & Trimetazidine!".

Sinner, who did the traditional Wimbledon dance with fellow winner Swiatek, addressed backlash by in an interview with the BBC.

"Well, me and Iga, we actually talked yesterday about this, and we've been celebrating in a way even more, because it was a very difficult time for her and also for me, and only me and my team and the people who are close to me know exactly how it went," he said.

"There are always going to be some people who believe in you and [who] do not, but this is in everything. So yeah, in a way, it's very special, because it was very, very stressful the time on the last four or five months."
