Boss Ronny Deila is looking to engineer Celtic's first Europa League win tonight in what he admits is Group A's most difficult fixture - away to Fenerbahce.
The Hoops have no chance of qualifying for the knockout stages after taking only two points from the first five fixtures while the home side, who lost their opening match at home to already-qualified Molde, need only one point to stay above Ajax to guarantee joining the Norwegian side in the last-32.
The Norwegian, speaking at the Sukru Saracoglu stadium before his side trained, was asked if the trip to Istanbul was the toughest test in the section.
He said: "I think so, I think it is the toughest game. We are playing a very good team and it is a tough place to come to win.
"But we have seen that other teams have come away from here with points so everything is possible.
"It's always important to win and if we can get a victory it'll be a big achievement.
"It will give us a lot of confidence to go into the domestic league as well.
"It is important that when you are away in Europe you defend well first of all and when we get the ball we have to make some problems for them.
"We want to be very clear in how we defend and how we attack."
At the same time as looking for a morale-boosting win, Deila might be tempted to give more game time to fringe players such as midfielder Scott Allan but he insists he will "not experiment a lot" with his side.
The former Stromsgodset boss said: "We will play the team we think is the best."
