Girona lost five matches including getting beaten by Sturm Graz, their whole European experience is close to zero, and more important than that they are mathematically out of the Champions League since they only have 3 points and the team placed right 24th has already 8 points, it would be impossible for City Eindhoven and PSG to not make a single point and at the same time no other team below to make any, at least victory.

So, why would Girona bother with that match when they should focus on catching a UEFA place in the Spanish league?
You don't have to analyze only past performance, you have to think what's at stake and why would they even play at their max since there is nothing to gain?
