The Scottish Premiership giants are third in Group B with three points from two matches.
Brendan Rodgers’s side are level on points with second-placed Bayern Munich and three points behind leaders Paris Saint-Germain.
Celtic goalkeeper Gordon, 34, believes that the Hoops can finish second in the group and progress to the last-16 stage of the Champions League.
“That result is big for us,” Gordon told The Scottish Sun while refereeing to Bayern’s 3-0 to PSG in midweek. “Now we need to try and go one better and get something from Bayern Munich.
“Second place is NOT gone for us. We know we’re up against two unbelievable teams to try to get that second spot. But we have given ourselves a chance now.”
Bayern may have lost to PSG and may have sacked Carlo Ancelotti as the manager, but there is no doubt that there are a much better team than Celtic are.
The German giants have much more experience of playing and succeeding in the Champions League, and it is hard to see the Hoops finishing ahead of them in the group.
The way Celtic collapsed against PSG at Celtic Park underlines that there is a massive gulf between them and the big teams in Europe.
