I know ~zero about soccer. I do know American football. And there is one small thing that I detest about both of them:

When a player scores, rather than expressing joy with their teammates (as in ice hockey,) they immediately act as if they've never met anyone else on the team (and in soccer, even run *away* from their teammates, so that the crowd may appreciate the glory of their accomplishment unimpeded!)

If I were a coach, I would quickly extinguish this behavior.
