I'm only echoeing what many others have said, it is a logistical nightmare to get there what with having to apply for visas, pay crazy money for flights and then you'll be lucky to get a hotel not to mention a match ticket if you don't have one, some United mates of mine have tickets and plan on going but haven't booked yet as they are trying to suss out how to get there on the cheap and it's proving very difficult, id love to go with them for the experience but i wouldn't be prepared to pay insane money for tickets, money i haven't got and Moscow wouldn't be on my list of plasces to visit anyway,maybe someday when they make it easier for people to visit there without the need of paying for visas.
its called football. its a business. if they're mug enough to pay silly money to watch a match, then thats perogative. even if they boycott, some other mug will probably take their place.
thats price you pay for "supporting" a big sucessful club.
i doubt the Russians will be losing any sleep over your non-visit.
i think we should organise a boycott of the european final just because the ruskies make people PAY for visas...
