Maybe the lower ranked teams should have a separate tournament or something, at the moment these games are just a waste of time.
I'm sure it's a lot of fun for the guys playing, and also the football fans in the stadium to be able to play against/watch those world class football players live.
Of course they don't have a chance, but that's not the point. Winning isn't always the most important thing.
You could just as well ask "what's QPR and Swansea doing in the Premier League? Why even bother when they'll just get kicked in the ass anyway?".
