Frank McAvennie has slammed Nick Walsh’s refereeing display as Celtic lost 4-1 to Rangers at Ibrox.
The former Hoops hitman, speaking exclusively to Football Insider, was left fuming by the decision to show Callum McGregor a second yellow card in the first half.
McGregor brought down Ryan Kent and Glen Kamara in the first half with the latter challenge resulting in a second yellow moments after the Gers opened the scoring.
Walsh, 30, took charge of his first Old Firm game and it wasn’t long before he had some key decisions to make.
McAvennie was left furious with Walsh’s decision and claimed that ‘the game has gone’.
When asked if he thought the sending off was the right call, McAvennie told Football Insider correspondent Ben Wild, “No, I thought it was terrible.
“For me, the game has gone. I know people call me a dinosaur but football is still a contact sport.
“He [McGregor] made it easy for the referee because he went to ground but this is Callum McGregor we’re talking about.
“He’s not like Scott Brown, where the ref looks for their challenges. When I was playing that wouldn’t have even been a foul.
“He barely touched Kamara. It wouldn’t have made any difference [if he stayed on] let’s be clear.
“But the two bookings, it’s crazy. It’s stupid. Who is teaching these referees? It’s embarrassing.”
Celtic have failed to win an Old Firm clash this season, losing four and drawing once in the league.
In January’s Old Firm, McGregor also made headlines for the wrong reasons as his own goal handed Rangers a 1-0 win.
