Celtic look in serious danger of being dumped out of the Europa League after their disappointing display against Sparta Prague in Glasgow last night.
The Bhoys were completely outplayed by the Czech side, despite coming into the game as favourites, losing 4-1.
It was yet another poor defensive display from Celtic who are struggling to get the results they need in important games this season.
Results against AC Milan, Ferencvaros, Rangers and Aberdeen have not gone their way and this was the latest example of their troubles at the back.
Indeed, one former Scotland international was not impressed with how Celtic performed defensively.

Michael Stewart for coverage of the game when he made it clear that Celtic are not going to be turning their form around until these defensive issues are sorted.
“Celtic’s problems won’t be solved until they learn how to defend properly,” he stated. “Otherwise they’ll never give themselves a chance to win a game. Some of the defending tonight was hopeless.”
Celtic have now conceded 14 goals in their last six games and the arrival of Shane Duffy from Brighton in the summer has seemingly done nothing to strengthen them at the back.
It is looking clear that Neil Lennon has a lot of work on his hands to get his team solid again, with this leaky defence likely to see them struggling for much longer going forward.
If Celtic cannot turn things around at the back, then Stewart is right, this form is likely to continue.
