Daniil Medvedev says he suffered with 'sickness and weakness' during his bout of Covid-19, but he is confident he is back to full strength now.
Medvedev tested positive for Covid-19 following a practice session with Rafael Nadal ahead of the Monte-Carlo Masters last month, prompting him to immediately withdraw from the tournament.
He was also unable to play in Barcelona the following week, meaning the Madrid Masters will be his first taste of clay action this year.
However, he has revealed that he did not get the asymptomatic version of the illness as many other tennis players who tested positive did.
"I felt some sickness symptoms," Medvedev explained. "It was like a strong cold, you know, or something like this.
"I had some nose and throat blocked a little bit, weakness for a few days but not more than that.
"Coming back was not easy for first four, five days, especially after laying in your bed at home.
"I feel like I had a good one week and half of practice. I just won doubles, so everything seems positive. Of course, I am looking forward to playing here."
The doubles Medvedev refers to was the first round of the Madrid Masters, in which he and Marcelo Demoliner beat British duo Dan Evans and Neal Skupski in the first round on Sunday.
