Manchester United and Manchester City players went head to head in the tunnel as tempers flared after Sunday’s derby.
Jose Mourinho confronted City shotstopper Ederson, with punches then being thrown by players on both teams in the aftermath.
The incident has echoes of the famous Pizzagate fight in 2004, when Sir Alex Ferguson had pizza thrown over him by then Arsenal star Cesc Fabregas.
And Wenger has now had his say on the fracas, using sumo wrestlers as an example of showing sportsmanship at the right time.
“It is part of the intensity. It can go overboard,” he said.
“It happened to us. It happened to us. Hopefully you commit 100% to the pitch and are an angel after.
“I don’t know what happened really. It is difficult to take to see the 100 per cent celebration on the other side. It is an experience that’s a little bit offensive.
“That’s why I admired sumo in Japan because the guy who wins does not show his happiness out his respect for his opponent.
“Is it something we can copy? I don’t think so. It’s not part of our culture.”
Fabregas confirmed earlier this year that he was the Arsenal player that threw the pizza over Ferguson.
“Yes,” he said when asked if it had been him.
“All of a sudden, I heard noises (from the tunnel) and I thought what’s happening?
“So I go out with my slice of pizza and I saw Sol Campbell, Rio Ferdinand, Martin Keown… everyone pushing each other.
“I was like, I want to get in but I don’t know how to and I threw… peeew… just threw it. Once I saw it was hitting, like, who it was hitting, which I didn’t mean…”
