After their humbling at the hands of Borussia Dortmund on matchday two, Celtic had found their sea legs in this tournament with a gritty draw away to Atalanta and a classy display to sweep aside RB Leipzig in Glasgow.
The energy, control and attacking verve display against the Bundesliga side was all on show again – unfortunately for Brendan Rodgers it was all being displayed by a Brugge side who took control of proceedings in the first half.
The visitors had served notice of their quality by beating Aston Villa and they oozed confidence as they continually passed through and around the Celtic press, much to the frustration of the home crowd.
Jutgla was lively throughout, asking questions of the Celtic defence, and the midfield duo of Hans Vanaken and Ardon Jashari were dictating the play as Celtic struggle to find a foothold in the match.
It was no surprise when they took the lead, but the manner of it certainly was.
Celtic attempted to play out with some high-risk passes, only for Carter-Vickers to lose his bearings, and sight of his goalkeeper, and pass the ball past Schmeichel and straight into his own net.
It was a calamitous way to concede and captain Callum McGregor gathered his men in a huddle – normally purely a pre-match ritual – to try and get their heads into a game that was passing them by.
Brugge passed up glorious chances to double their lead after the interval, with Maxim De Cuyper thwarted by the fingertips of Schmeichel and Andreas Skov Olsen blazing over – and will feel a more clinical edge would have seen them depart with all three points.
