It's difficult to definitively pick out what irked the Rocket but he clearly wasn't happy at all. The referee had to apologise to both competitors before the match continued on.

However, the audio suggests that the referee had accused him of some sort of unwelcome gesture.

“What gesture? Tell me, what did you see? Tell me, what did you see?" Ronnie can be heard saying.

“You saw nothing. You saw nothing. Go and look at your camera. You saw nothing. Don’t start, don’t start. Go check your cameras.”

Later, O'Sullivan accused the referee of simply stirring up trouble:

“I think he’s just seems to be looking for trouble, you know," he said, speaking to Eurosport.

“I just get a vibe from the guy. They have hundreds of cameras out there. They can go and check them all. Slow-motion them down."

O'Sullivan, in pursuit of his seventh world title, will enter the final day of the tournament with a 12-5 lead over Trump.
