Celtic are out of Europe and will have to wait until next season's campaign to have another go at securing continental football after Christmas.

A really difficult group in Barcelona, Borussia Monchengladbach and Manchester City was too much for the Bhoys, who will finish bottom of Group C.

There's one last matchday, though, and Brendan Rodgers' side face one of their toughest tests, an away trip to Manchester City.

The Glasgow outfit produced an exceptional performance against Guardiola's side in the first meeting this season, taking the lead three times before being pegged back on each occasion. Can they go one step beyond and secure victory this time?

What's in it for Celtic to go all out for the win? In what is essentially a meaningless fixture, should Rodgers' team put it all on the line to secure victory?

Here are our THREE reasons why the game with Man City still matters for Celtic...

Huge travelling support

Where Celtic go, thousands follow, and tonight's match will be no different in Manchester. With thousands expected to make the trip from Glasgow. At the very least they'll be expecting a committed performance from their team as a reward.

Every game matters to the Hoops faithful and most will care little that there's nothing on the line. For them, it's all about showing Celtic are one of biggest clubs around, both on and off the field.

If Rodgers' side can produce victory, it would give everyone in attendance a memorable night and be one of the occasions of the season, despite it meaning little in reality.

No wins yet, prove your worth

Celtic haven't won a game in this season's group stage and if the remains the case it wouldn't sit well with the team, the manager, the club or the supporters.

If nothing else Celtic have pride and going out with three points would at least show Celtic had a fighting chance in Group C.

The Bhoys have never ended a Champions League campaign without a group win so it would also be a bad precedent to set and reverse a long history of good performances in the competition.

Despite meaning nothing in terms of qualification, we're sure Rodgers' side are aware of the responsibility they carry to Manchester.

Money & co-efficient

Perhaps unlike some clubs in the competition, Celtic don't take the financial rewards for granted. With a poor domestic TV pool to draw from, every penny counts across the season for the Bhoys.

With €1.5m on the line per group win and €0.5m for a draw, points represent a significant prize and in turn motivation for Rodgers' men. In the market Celtic operate in, a win could be the difference between bringing a player into Celtic Park or not.

Co-efficient points matter too with Celtic the only side in Scotland contributing significantly to the country's total. There's been a slide in the last ten years with Celtic having to face a number of summer qualifiers.

It wasn't always like that, but if it's to change then the Bhoys can't afford to take any European game for granted and must eek out every point they can to build the total.
