When I watch a live match that I am not in I will always support the team playing a team I need to lose or a team playing a bot.
I am wondering if players will support a team playing against a U.S. player. I have never had a manager support me during a game and will usually have at least one (always non-american manager) supporting the team I am playing during prime hours. I may be thinking a bit arrogantly as an 'Ugly American', but I do think it is because where I am living.
Any other American players notice that?
