This is bigger than football it is about freedom and values. If all the major European clubs threatened to pull out of Europe next season and start their own alternate competition UEFA may back down but it won't happen, I don't know if any other clubs have even made any noise about it but this could happen to any club. Arsenal and Chelsea have a duty to their shareholders and aren't going to risk losing a potential £100 million champions league campaign next season seeing as English clubs have a really good chance of getting far based on this seasons form.
Basically UEFA are a disgrace and should make a statement to the world by moving the final to elsewhere but they probably won't as money talks as usual.
So, if it is to go ahead as planned, it would be nice to see Arsenal and Chelsea fans unite in showing their disgust to the world TV cameras throughout the game by displaying neutral coloured banners and scarfs etc......they could produce rainbow coloured Arsenal and rainbow coloured Chelsea scarfs to show that no matter what colour your team wears, what colour people skin are or no matter where they are from they are equal.......every TV commentator throughout the world would have to explain the scarfs. Both clubs could easily afford to make 5000 of these each and give out to the fans for free
