He's called Manuel Pellegrini a "f**king old c***" and pushed Arsene Wenger on the sideline. But Alan Pardew's headbutt attack against Hull City's David Meyler was mis-behavior on another level.
The Newcastle manager has been fined €100,000 by his club and also faces a potentially lengthy touchline ban.
"He's completely uncontrolled on the sideline. It's kind of weird to see. If you do it once, and at an absolute push, twice you think that's out of order. But he is a serial offender at this sort of thing. This is obviously the worst thing that he's done," said Pat, who thinks that the Newcastle manager should be on a last warning.
But will it affect his moral authority in the dressing room, in terms of instilling discipline?
"It's sad to say that the authority comes from only one thing: him being successful. All the other stuff is moonshine really. People say he might lose his moral authority. Okay, he tells a player he's going to fine him for doing something wrong and the player might turn around and say 'you headbutted somebody'. He can say 'I paid my fine, so you can pay yours'."
Nevin also touched on Stoke's manner of playing against Arsenal on Saturday.
An aggressive approach helped the Potters to a 1 - 0 win over the Gunners, with Charlie Adam charged for a stamp by the FA and Steven Nzonzi branding Arsenal soft.
While admitting an overly-physical approach is generally punished more heavily by referees nowadays, Nevin feels the rules are "slightly different at Stoke" who already have the worst disciplinary record in the Premier League this season.
"They're kind of allowed a bit more by most referees because it's almost accepted that that's their style of play; that they will be rougher, more physical so there's a little bit more allowed. It shouldn't be. Everything should be the same for every single team. I've watched Stoke a few times this season and I'm not saying they're absolutely animalistic, but they will take it as close to the edge as they possibly can," said Pat, likening it to the way non-league clubs get a little bit of leeway.
Pat believes Arsenal need to play their own game against Stoke, rather than meeting fire with fire.
He also discussed the lack of competition in the Scottish Premier League and why the situation is a "catch-22".
