Gary Caldwell admits there are no excuses for Celtic's poor away record in the Champions League group stages.
The Bhoys have now gone 18 games without a win on the road in Europe's elite competition after Tuesday's defeat against Aalborg.
Despite taking the lead in Denmark, Gordon Strachan's side fell to a cruel own goal as Caldwell himself put through in his own net to complement Caca's earlier deflected equaliser.
Caldwell, though, feels it is 'too easy' to blame misfortune, saying: "You can't keep saying it was bad luck.
"Ultimately, we weren't good enough to hold on to the lead that we managed to get or maybe even get the second goal that would have killed the game off.
"But we can't say we were unlucky - that's too easy.
"We have to look at ourselves," he added. "We were probably the better team on the night but unfortunately in football, if you make mistakes it can cost you.
"It's a massive disappointment to have been in the position we were in and then throw it all away."
Caldwell admitted to being saddened and frustrated after his own goal sent the Hoops crashing out of Europe all together.
"Glenn (Loovens) tried to clear the ball and it hit me on the knee and sneaked inside the post and we were out.
"It's hard to take," he added.
"We wanted to be in the last 16 of the Champions League or at least still be in Europe but we are not.
"We have to be big enough to bounce back from it and make sure we are in this competition again next year."
