The experience Israel international was already on a booking when a furious reaction to simulation from Midtjylland winger Anders Dreyer saw Bitton poking the eye of the Danish winger.
His reckless, rash decision saw Celtic down to ten men following the Bhoys’ opener, with Bitton’s teenage compatriot Liel Abada painting a different story in terms of his contribution to the team.
The Israeli debutant impressed with fluid trickery and a debut goal to send Celtic Park into thunderous cheers in an all-action display worthy of the no. 11 shirt.
However it was Abada that made way, having unleashed his heroics in Paradise, in order for Postecoglou to stitch up the gap in the Bhoys’ back line.
Dane Murray came on for Abada in order to fill the Bitton-shaped void in a Celtic debut and looked comfortable for much of the game.
The much-maligned Dreyer was himself sent off for a second booking following a second-half simulation incident, having seen a first yellow for his clash with Bitton.
Later, a misjudged free-kick by Vasilis Barkas saw an Evander set-piece elude the squad and ricocheting into the net off the post.
The cagey, aggressive affair prompted Bitton to take responsibility for his actions on social media as he posted a statement on his Instagram story:
“This is my platform to speak and I just want to say sorry. I lost my head for a second and got punished for that… sorry again.”

For many Celtic fans, sorry will not be good enough.
The seasoned professional, who captains his country, will have faced an abundance of tense moments in his career and letting blood rush to his head is a let-down for his team.
Fans will have expected better from Bitton.
