The Arsenal legend and Petke had to be separated by teammates earlier this week.
"What happened with me and Henry? Listen, Thierry Henry is one of the most passionate and fiery people I've ever been associated with. And unless you guys have been under a rock for the last 13 years, I'm pretty passionate and lose my head a lot too," said Petke.
"Very normal stuff, there's really nothing to report. Nothing to report. It happens all over the world. As you saw, Thierry and I talking fine today, we had a great conversation after practice yesterday, both on the same page, both ready to roll."
