After the game, the Celtic boss expressed his disappointment, as he told reporters: "It’s bitterly disappointing because we were on the right track last season, working very well and playing really good football. To not be in there this season, it’s a huge blow for us. I think we all know the consequence. If you don’t win the tie, then you drop into the Europa League. So we want to be in the Champions League, but we aren’t.
"So the Europa League’s still a prestigious tournament, but we missed a massive opportunity here over these two games. It is a long journey. You’d rather be travelling and having won the game, but we haven’t."
