The supporters thing isn't really 'sad' or in any way unsportsmanlike.
The whole point of having 'friends' is to exchange reds/greens/blues/skills and to improve possession. I never ever ask anyone to watch my games, but I'll usually have around five or six at any one time turning up to support me, that's just how the game is.
My advice is to send out about 30 'friend' requests to active players in lower or higher leagues and you too will be able to annoy opponents who have no one supporting them!
