With followers protesting towards the membership’s board in the beginning of the sport and later sarcastically cheering Schmeichel making a save, the ambiance at Parkhead was removed from harmonious.
“It’s bitterly disappointing,” former Celtic captain and supervisor Neil Lennon stated of the jeers directed at Schmeichel.
“He had a bad night but it still doesn’t warrant that kind of treatment.”
Thursday night was the newest in a string of perceived errors made by Schmeichel, following Joe Hugill’s looping header for Kilmarnock final weekend and Jonathan Rowe’s effort for Bologna final month.
Perhaps unsurprisingly, Celtic closed ranks round their embattled goalkeeper post-match.
“It’s a tough evening for us,” interim supervisor Martin O’Neill stated. “On paper, 4-1 looks pretty poor.
“We had been masters of our personal downfall in many respects, conceded some poor objectives.
“Kasper [Schmeichel] has made some great saves while I’ve been here. This is a collective, there’s no doubt about that.
“We performed Feyenoord in a recreation we most likely needed to win and he made an unbelievable save, in any other case we would not be right here taking part in tonight.
“I will think about all sorts of things [before the next game], but Kasper has done really well since I’ve arrived at the football club, in both spells.”
Captain Callum McGregor added: “Everyone makes errors.
“Kasper has been wonderful since he is come to the membership. He’ll mud that down. We win as a group and lose as a group.
“There’s no blame, he’s made so many big saves for us. He’ll bounce back for sure.”
