Tournament director Richard Krajicek admitted Rotterdam may have to change following criticism from Alexander Zverev.
Zverev crashed out of the tournament on Wednesday after he lost his opening match. It was his fifth career entry there and he has only won three matches at the event.
After the straight sets defeat to Alexander Bublik, Zverev commented that he dislikes the conditions in Rotterdam and always has, and that he has not even won a set in practice.
"I haven’t done well here in the past and to be honest if the conditions don’t change a little bit, I don’t think in the future I’ll do too well here either," Zverev said.
“I’m not as upset about the match as I usually would be in another tournament because I just don’t feel well here.”
Zverev's point of view was backed by Stefanos Tsitsipas, who said it takes 'a lot of effort to hit a winner' due to the speed of the courts.
Far from taking it personally, though, Krajicek says he is keen to work with the players and he will take their comments seriously.
"It’s not nice to hear, but maybe we should see if we can make the court faster," Krajicek said, as quoted by Nos.nl.
"Anyway, it’s something to think about if his criticism is valid.
“We have to do something with this as a tournament. Of course you don’t want Zverev or other players to think at some point: 'just leave Rotterdam alone.'”
"On a scale of five, our speed has been on the third level for a long time, so about average."
