Centre-back Liam Scales had the most touches of any Celtic player with 121, ahead of left-back Kieran Tierney (79) and goalkeeper Sam Johnston (69).
Goalkeeper Baur admitted they didn’t do enough to win and lost when asked what needed to change. “The way we played in the second half, the last 30 minutes, we deserved it in the end,” Baur said.
When asked if he knew why his team fell apart in such a way, he replied: “I can’t tell you, I’m sorry.
“You might score, they might score, a good team — then you’ve got to take back control, keep the ball a little bit longer to take the momentum away from them. You’ve got to break it down.”
Celtic failed to regain control, failed to break Celta’s momentum and ultimately paid the price.
Former Celtic goalkeeper Pat Bonner told Sportsound: “I think Celtic individually and collectively are not good enough to take on a team who are eighth in La Liga.”
“They moved the ball really well and Celtic couldn’t get close to them.
“They are not good enough at this level. Celtic pay big money for some players because the fans demand it and then they come in and they are not good enough.”
Their next trip to Europe is on November 5 when they host Beşiktaş, trying to overcome their difficulties on the continent. Whether they can is another matter.
