When I am theoretically a 'neutral' I support the team where it means more to their people, generally speaking. For example, a 2-1 win to Bosnia with a wonder goal from Messi would have been nice last night. Argentina are awesome and Messi is in particular, but they will always be half decent. For Bosnia last night had so much significance and it wasn't just another group game at another world cup.
Tonight, I want Ghana to win because I have them in my sweepstake. I wanted Nigeria to win for Shola and for the people of Nigeriewcastle.
