Of course the money plays a role, but the amounts you mention are for winning the cup. Small clubs from small countries will never again win the CL, as long as football is directed by people like Blatter and Platini, who again stated recently that he is against all forms of technological help. This means the CL will become predictable as hell, like in the last five years. The variation in the semifinals, and even in the quarter finals is saddeningly low.
EL and CL are more interesting with more teams from different countries, so that's why I support all teams from my country, even the rival team. Because when your country loses enough points on the UEFA ranking, you lose a spot in the EL or CL, whiuch leads to less variation again.
Of course I'd rather see a team I don't really care about win a lot of games (like AZ Alkmaar this year) instead of the rival team, but if the rival team is the only team left in EL or CL, I'll hope they win most games, just so we get a better chance to get to EL or CL next year.
