Celtic captain Scott Brown “will be raging” with his teammates for the manner in which they lost against Rangers, according to Frank McAvennie.
The Parkhead legend, speaking exclusively to Football Insider correspondent Dylan Childs, said that “something is not right” and urged Neil Lennon’s side to “look in the mirror” after Saturday’s performance.
Connor Goldson netted twice as the Gers won the first Old Firm clash of the 2020/21 campaign 2-0 to move four points clear of the Hoops, who have one game in hand.
It was the first time since May 2009 that Celtic have failed to register a single shot on target in a league game.
McAvennie described the Bhoys’ next Scottish Premiership fixture at Aberdeen as “must-win”.
“That was the problem, the manner of the loss,” he told Football Insider.
“I saw that the shots on target and intensity have been going down and down over the past 10 games. Something is not right.
“People will look to blame something, maybe the crowds, but I think you need to look in the mirror. The boys will know.
“The first thing you have got to do is win your own individual battle and then you can start playing. We did not win any of the battles on Saturday. Rangers were better all over the pitch and that is what was disappointing.
“I know Lenny and that would never have happened to him as a player. I know Scott Brown and he will be raging. That is two big voices in that dressing room.
“They know they have a massive game on Sunday and that is a huge, must-win game.”
