There has been a couple of surveys done world wide in last couple of years(2009 I think)that listed the clubs with the largest registered number of supporters, this I agree doesnt include the fly by nights who follow a player from their country from one club to the next, but, it counts as far as the term can be applied "real" fans. The club with the most had 8.5 million fans and that was Fernerbache, Manure were second, Barca third Madrid 4th, Liverpool 5th and RANGERS 6th- the other mob didnt make top ten If someone can be arsed you can find the linl and post on kerryfail to put an end to their delusions
