Alexander Zverev says he now 'can't afford to lose' at the ATP Finals after his defeat to Daniil Medvedev.
Zverev was easily beaten 6-3, 6-4 in his opener, and now has the unenviable task of having to bet Novak Djokovic to progress to the semi-finals.
He also has a match to come against Diego Schwartzman, but he is very aware of the stakes.
"I need to play better. I need to be better on court. Because if I play like today, I’m not going to win any matches here this week.
“Now I can’t afford to lose. I need to beat Diego, I need to beat Djokovic to have a chance to go to the semi-finals.
"I’m going to try to do that. But with how I played today, it’s going to be difficult to do.”
Zverev was some way short of his best against Daniil Medvedev, and he was happy to acknowledge that himself.
“My serve was not quite there today,” he said. “All in all, it wasn’t a good match for me. I think since the restart of the season, it was one of the worst ones.
“Credit to Daniil. He did what he needed to do. I mean, the underarm serve paid off for him. Great job to him.
"I think maybe he was a little bit nervous in the beginning, but then he picked up his level.
“But, yeah, it was not good enough to beat a Top 10 player today from my side.”
