I tell you what's better than booing the anthem.... vote with your wallet like me and make a decision that you can't afford to go to every game and boycott the tournament.
I hate the tournament beyond description, I hate fact it's seeded, I hate the fact UEFA only want Barcelona, Real Madrid and Bayern plus one British team (excluding City) in the semis, I hate the fact it is nothing but a money spinning tournament for them, I hate fact they take money from beer companies yet you can't buy a beer at the stadium... why not? you can in leagues and Domestic cup competitions... so fuckin hypocritical, bent and rigged it's untrue. They will never ever see another penny from me.
But if I'm in the pub and it comes on..... I'll always boo the shit tune.
