Brendan Rodgers was hopeful his side could overcome Salzburg in their crunch Europa League tie on Thursday night.
Celtic knew that a point would ensure they qualified from Group B as they welcomed the Austrian side to Celtic Park.
“We know it’s a tough test for us,” said Rodgers before the game, per the Evening Times. “But with everything and knowing we need a result it’s not workable to play for a draw.
“It has the feel of a big game, a game that we are really, really looking forward to. And rightly so because of our form, and not just how we have been playing in the last 2-3 months.
“In European competition, we have got better and better as the competitions have gone on. We maybe start off a bit slow, but we have always got better.
“We know it’s tough test for us but we know we need a result. It’s not workable to play for a draw.
“It should be an incredible atmosphere, the wall of noise that comes from the stadium.
“The Salzburg guys, some of them won’t have experienced it before and for us it’s a great energy for our team and how we play. So we look to get the job done.”
However, it did not go to plan for the Scottish side.
Celtic looked as if they would hold on to progress to the knockout rounds, but Moanes Dabour broke the deadlock 23 minutes from time.
Regardless of the setback, Celtic had time to restore parity and ensure they would finish second in the group.
But, a moment of madness from Craig Gordon gifted Salzburg their second.
Picking up the ball in his box, Gordon went to roll it out but it was immediately intercepted by Fredrik Gulbrandsen.
Gulbrandsen then steadied himself before dispatching into an empty net.

Olivier Ntcham managed to pull one back after coming off the bench but it only proved a consolation for Celtic.
Fortunately, Rosenborg managed to score a late equaliser against RB Leipzig to ensure that Celtic would finish second in the group.
That is some consolation for Gordon, but he will still look back on the night with some very bad memories.
