Both Chris Sutton and Alex Rae accused each other of being "cheerleaders" during BT Sport's coverage of Celtic's 2-0 win against St Mirren on Wednesday evening.
It was Sutton who fired that shot first, saying that Rae is a "Rangers cheerleader". Rae later hit back telling Sutton, "You're a cheerleader for Celtic these days". The former Celtic player later tweeted that he wished Rae would "get his own patter".
It came amid a discussion about the weekend's fiery Old Firm derby win for Celtic.
"Some of the things which came out after the game have been slightly concerning," said Sutton.
"Steven Gerrard saying that Celtic are playing the victim card; this is a guy who on the first day of the season was complaining about conspiracy theories with referees. If I came over and punched you and elbowed you in the face, Daryl, I would say that you would be the victim in that situation.
"We saw massive deflection tactics. People talking about Scott Brown at the end of the game, who did very little. This is a Rangers team who over the years have celebrated with the huddle."
Sutton then pulled no punches when speaking about Rangers' Andy Halliday.
"We saw Andy Halliday, a player who they were talking about at Ibrox getting a DVD out about him because he made one tackle which was 80/20 in his favour and has made a couple of throw-ins this season," Sutton.
He's a bang average player who's trying to use these things to create melees. Do your business on the pitch. You've had one win the the last three seasons [against Celtic].
Let me tell, you Rangers haven't made progress this season. They've lost three times to Aberdeen. Kilmarnock have been better than them in the league, Rangers haven't beaten Hibs. All this nonsense, 'Steven Gerrard has made progress' - he's 13 points behind and they're out of the cup competitions. I've never heard so much waffle.
Rae argued that Brown had let himself down when celebrating in front of Rangers fans following Sunday's game.
"He doesn't have to do it in front of them," said Rae.
"This is the Celtic captain we're talking about here. Have a wee bit of dignity, walk away from the situation and celebrate with the 59,000 fans. He doesn't have to wind people up."
"So, we blame Scott Brown for everything, don't we?" replied Sutton. "It's OK when Rangers players do it when they've done it before. Oh, wow. Blame Scott Brown for everything - that's embarrassing."
It was then that Rae suggested Sutton had become a Celtic cheerleader.
