There really is no love lost in tennis it seems…
In what might be the most crassly spoken sentence ever formed on a tennis court, Aussie bad boy Nick Krygios told Stan Wawrinka, "Kokkinakis banged your girlfriend. Sorry to tell you that, mate."
Swiss champ Wawrinka has since taken to Twitter to address the comments, posting “What was said I wouldn’t say to my worst enemy. To stop [sic] so low is not only unacceptable but also beyond belief.”

Meanwhile, Krygios has been defending his remarks: "He was getting a bit lippy with me. Kind of in the heat of the moment, I don't know, I just said it.”
Not that he’s the only sportsman to have crossed the line with a poor piece of sledging.
