Chris Sutton reckons Ally McCoist is "jealous" of Kyogo Furuhashi - after the Rangers hero unleashed a tongue-in-cheek rant about Ayo Obileye's red card against Celtic.
The Livingston defender saw red in the dying stages of his side's clash with the Hoops last weekend when he swiped a hand towards the striker's face.
There appeared to be minimal contact but Kyogo went down leading to the defender being sent off.
Celtic were awarded a penalty which Giorgios Giakoumakis missed in the 0-0 stalemate.
But McCoist didn't appear to be over it as he unleashed a sarcastic rant on BT Sport's Scottish Football Extra.
With a clearly sarcastic tone, Rangers hero McCoist expressed concern for Kyogo 's health - and jokingly called for the Livingston defender to do time behind bars.
McCoist said: "I love Kyogo, but I've got to say, I'm not normally critical...but I've got to criticise the Celtic medical team.
"It was a disgrace, the lack of information that came out over the weekend about Kyogo's health. after that challenge from Livingston.
"It was a shocking challenge. I'm a Rangers man, but I was genuinely concerned about his welfare.
"On that challenge itself, we can't have heard the last of this. I fully expect the Procurator Fiscal, or the director of public prosecution, to get a hold of that centre-back.
"If he's not banged up in one of our high security prisons over the festive period then there's something wrong with Scottish football."
He finished with his voice breaking into a laugh: "Have I made my point?"
Sutton then added his two cents as he accused McCoist of sour grapes over Kyogo, who just notched his 11th Celtic goal against Ferencvaros.
He quipped: "I can see the jealousy oozing out of you, but what a player. He's the best player in Scotland this season, no doubt about that.
"Brilliant piece of business. Three signings from Ange Postecoglou and they're all firing."
Joking aside, however, McCoist concluded with a sincere message that branded Kyogo "a breath of fresh air."
"I do love him. I was having a laugh there, but he's excellent.
"He scored a brilliant goal and he was unlucky with the other one where he went through and tries to dink it over the goalkeeper.
"He's been a breath of fresh air."
