The Bhoys sit third in Group B ahead of Thursday’s home clash with RB Leipzig with just three points to their name.
Brendan Rodgers’ men made the perfect start to their Europa League campaign with a victory at home to Rosenborg but back-to-back defeats away at Salzburg and RB Leipzig have left them in danger of being eliminated.
Celtic, who are priced at 26.00 to win the Europa League, also endured a tough start to their domestic campaign, having lost two of their first six games, but they have recovered to win the last six.
Their resurgence in the Premiership has led Gordon to believe they can also improve in Europe and he has stressed the importance of performing on home soil.
Gordon said: “We believe we’re still in the group and there were things we saw from them, and in our performance, that gives us hope in Glasgow.
“The home games were always going to be vital for us. We’ve got Leipzig and Salzburg to come to Scotland, while we always felt we’d need to pick up something away from home at some point.
“We haven’t managed to do that so far but there was some encouragement in Germany. “We created chances. We didn’t managed to take them and that’s what you need to do at this level. That could be the difference at Celtic Park.”
