The German progressed to the semi-final of the tournament in the early hours of Friday morning, beating the Belgian in three sets: 4-6, 6-3, 3-6.
And it appears Goffin didn't like the attitude of his last eight opponent during their match.
Speaking in a press conference at around 1am in the morning, the world No 10 launched a stunning attack on Zverev to Belgian reporters.
“He doesn’t care a bit about others,” said Goffin, according to New York Times reporter Ben Rothenberg.
The quarter-final loser reportedly didn't like how Zverev changed his racket several times during their clash.

And the 21-year-old was accused of taking too much time between losing points, which hindered Goffin's focus.
And it seems tennis fans agree with the comment about Zverev's temperament.
One said: "He's right. I do not understand people who call me Zverev 'sweet'."
And another tennis fan said: "Zverev has proved he's pretty good at psyching out his opponents."
Zverev went on to beat Marin Cilic to set up a final with Rafael Nadal on Sunday.
