Neil Lennon branded Chris Sutton a "plank" after being mocked over his Celtic pronunciation.
The former Parkhead team-mates were involved in a light-hearted clash on Sky Sports after the 1-0 win for Celtic over Rangers at Ibrox.
And after a heated exchange with Kris Boyd over the problems at Rangers, Sutton turned his attention to mocking pal Lennon over his pronunciation of Gustaf Lagerbielke.
Butting into a conversation, Sutton said: "A quick one, Eilidh. For Neil, can he get the Celtic centre-back's name right?
"Lager-beaky? Who is that, Neil? Dear me."
Lennon was quick to fire back, though, responding: "Well, what is it then, smart..."
Sutton then said: "Lagerbielke, come on, you are better than that."
Lennon was unimpressed by Sutton's jibe and then fired back with an insult branding the pundit a "plank".
He joked: "I'm Irish, it's just my pronunciation. You obviously misheard it! I said Lagerbielke.
"We don't all speak as fluently as you Norwich people. Plank!"
Celtic summer signing Lagerbielke was at the centre of a major flashpoint as he was fouled by Cyriel Dessers before Kemar Roofe rifled home what he thought was the opening goal.
However, after a VAR review, Don Robertson overturned his call and gave the free-kick to Celtic.
On the incident, the defender said: "I took it [the ball] forward, with too many touches maybe, but I got fouled by Dessers and they scored but fortunately for us it was a foul and I thought so to. I could breathe after that.
"I thought it should never count. I am happy it was not a goal."
