Alexander Zverev revealed he nearly pulled out of the Monte-Carlo Masters beforehand due to an elbow injury.
The world number five has already won a title this year, beating Stefanos Tsitsipas in the final of Acapulco last month.
However, despite saying he felt most at home on clay courts, Zverev suffered an early exit in Monte-Carlo against David Goffin - although it may not have been all it seemed.
"Yeah, for the circumstances, I think it was quite a good match from my side," Zverev said after the match. "David played extremely well I thought.
"Yeah, I mean, with the elbow injury, with not knowing whether I'm going to play the tournament or not, I think it was quite okay.
"Of course, a little bit upsetting that I didn't end up winning the tiebreak, but that's just how it goes."
The injury itself is a fracture, as Zverev explained before his first round win in Monte-Carlo over Lorenzo Sonego.
He explained: "It's a small fracture. I'm still recovering at the moment, so I'm not at 100 percent. But I'm trying to get better from day to day."
Zverev has a busy schedule currently planned, with Munich next week, followed by Madrid and Rome before the French Open.
