Bleacher Report is taking a look at the most dedicated fanbases in World Football.

Clubs like Manchester United, Barcelona and Real Madrid are well known worldwide and have tons of fans outside of their own cities.

We aren't talking necessarily about the most well-supported clubs in terms of numbers, though these clubs fall into both categories. For this list we are looking at clubs whose fans are behind them 100 percent through the good times and the bad.

The statistical evidence, average attendance and so forth, alone shows how dedicated fans of some clubs are. While for others like Barcelona and Celtic, the club's origin and ideals etc., play a big part in how dedicated their fans are.

It isn't just clubs with dedicated fanbases, however, as international teams certainly have tons of interest in various countries. Since it's a bit hard to judge international fans versus club fans, the international teams have their own little mini-ranking as it were.

Here are the 25 most dedicated fanbases in world football.
