Chris Sutton has criticised former team-mate Neil Lennon in his decision to play Callum McGregor as left-back.
Sutton also believes the fact that John Kennedy not warning Neil Lennon about the result the last time McGregor played there – means he must take some of the blame.
Sutton writing in his column in the Record said: “The decision to play Callum McGregor at left-back was a mistake. That’s not hindsight. The evidence was already there.
“When Celtic went to Ibrox last December, Rodgers did the same thing and it was a glaring error.
“It ruined the balance of the team and seemed to mess with their heads. The rest of the players weren’t at it at all, as if bewildered as to why the manager would take their best midfielder out of the engine room and stick him at full-back.
“Lennon couldn’t understand why his team was so poor and passive during the first half against Cluj. I might be wrong but I can’t help thinking it was the same again.
“And John Kennedy should have been telling him this. He was standing beside Rodgers at Ibrox when it fell apart.
“If I was McGregor then I’d be devastated. This is a boy who was wanted by a top-half Premier League team because of his midfield talents and told he couldn’t leave because he was too important to Celtic.
“Yet he ends up shunted out of his best position in a huge game. It killed him and you would imagine it has done the same to Boli Bolingoli-Mbombo.
“Signed as the left-back for £3million, it was a move which must have told him that he couldn’t be trusted in the big game.
“It’s all right defending the boy in public as Lennon did last week. That’s commendable but it unravels if the next move is to drop him.
“There was an uncertainty about the whole night and I’m convinced it stemmed from there.”
