An independent tribunal accepted Sinner’s explanation that traces of the anabolic steroid clostebol had entered his body via a massage from his former physio Giacomo Naldi.

But the Australian Open champion, who needed a medical timeout when he lost to Daniil Medvedev in the Wimbledon quarter-finals, told ESPN: "It had an impact because I was often ill, I didn't feel much energy on the court, I think we saw this at Wimbledon for example.

"I went through sleepless nights thinking about it, and had some physical problems perhaps related to this. There were very difficult moments on the court, I didn't feel like myself, I wasn't happy.

"The process was very long and with time you feel a greater weight, the great wait for the end, the arrival of the results, it wasn't an easy period, but now I'm happy.

"But now I just want to move on, I'm not saying that everything will be ok straight away. but I hope to feel happy on the court again.".

Sinner tested positive twice in March of this year during the Indian Wells tournament. He was notified of the positive test results after the Miami Open.
