Alexander Zverev was suffering with coronavirus symptoms before and during his match against Jannik Sinner at the French Open, he has revealed.
The German was well below his best, losing 3-6, 3-6, 6-4, 3-6, and he asked for the physio on court before the match has even begun.
He later admitted that it was due to worrying symptoms consistent with Covid-19, and he shouldn't have even played.
"I am completely sick after the match with [Marco] Cecchinato in the night," Zverev said.
"Yeah, what can I say? I'm completely sick. I can't really breathe, as you can hear by my voice. I had fever, you know, as well.
"I'm not in the best physical state, I would say. I think that had a little bit of an effect on the match today.
'I warmed up today; I shouldn't have played."
Zverev was also asked if he had been tested recetly for coronavirus, but refused to answer, claiming it was because he had a problem with the journalist who asked it.
"I'm not answering you questions," he told Ben Rotherburg of the New York Times when asked.
"There is no chance I am answering your questions from what you have been writing about me over the past months. Absolutely no chance"
