I am writing a text about how the team "Leopard Trek" (Tour de France) is perceived by people in Luxembourg as a 'luxembourgish' team, even though it has an international roster of multiple countries. The only thing it has to do with Luxembourg is the few luxembourgish drivers it has and the fact that it is registered in Luxembourg.
The term I am trying to use is 'self-important', since I think it is kind of arrogant when people here speak of 'Team Luxembourg' or 'Team Schleck'. However, I think that the word would put the critic on the team (which is innocent) instead of the fans.
How would you describe a group of people (or a general situation), that only see their part of a common struggle/team/collaboration instead of thinking of themselves as a part of a whole.
