Novak Djokovic and Iga Swiatek were among the players who revealed their "tennis ick" in a funny promotional video for the US Open.
As the last Grand Slam of the year gets ready to begin tomorrow, Monday, August 28, some of the top-ranked tennis stars were asked about the aspects of the sport that they found the most annoying or off-putting in matches.
From grunting to taking a long time to serve, here's what the tennis stars had to say.
23-time Grand Slam champion Djokovic was the first player in the video, and his response was noise-related.
"Erm... Grunting. Too much noise. I get annoyed by that," he said with a laugh.
He was followed by world No. 5 Ons Jabeur, who revealed it was players saying 'C'mon' that got on her nerves.
"I don't know, the saying 'come on' too much annoys me a lot," she said, before jokingly adding, "But don't tell them [other players], they will do it."
Third seed Daniil Medvedev was next to disclose his tennis ick, saying it was when players take a long time to serve.
"I generally am someone who gets ready fast for the points. So in general, sometimes I just get bored when people get ready for the serve too long, because I stay there in return. I'm like, okay, let's wait, let's wait, let's wait," he explained.
