well my favorite sport is hockey, and many people here in switzerland think that this is also the most popular sport here (maybe together with skiing). but football comes close to it in popularity, even so i think it's not as interresting as hockey.

the good thing about football is, that there are many many international games, probably that's one of the reasons why it became so popular... at least that's my opinion about it. and i think almost everybody likes to see international games when his/her country is involved.
