Alexander Zverev had nothing but sympathy for opponent Matteo Berrettini after he broke down with injury at the ATP Finals.
The two played a high-quality first set in Turin, with the Italian crowd really getting behind Berrettini.
However, early in the second set the world number seven suffered an abdominal injury, forcing him to retire and throwing the rest of his tournament into huge doubt.
Berrettini himself has described it as 'the worst day of his life on a tennis court,' and Zverev had nothing but sympathy for both the player and the fans who had come to back him.
“I don’t really know what to say, because this is the worst feeling a player can have,” Zverev said.
“You play all year long to qualify for this beautiful tournament.
"For Matteo playing at home, this is the worst feeling I think he will ever have in his career.
“I thought the first set was incredibly high-level tennis. This is all not important.
"The most important thing is that both players at the end of the match can shake hands and are healthy. Today this is not the case.
"I think a lot of you guys, everybody here in Italy looked forward to seeing [Matteo] play all three matches, maybe the semi-finals, maybe the final."
