Fans won’t be returning to football stadiums anytime soon.

At the moment, matches being played behind closed doors is the best we can hope for. When supporters are allowed back in, it’s likely to be at a reduced capacity.

In fact, reports suggest that the entire 2020/21 campaign could be played in front of no fans.

As the saying goes: Football is nothing without fans.

Which is why Spanish outlet, Marca, have decided now was the perfect time to run a vote on which side in world football has the greatest fans in the world.

Hundreds of thousands of votes were cast and the best 40 sets of fans in world football have now been revealed. You may be surprised at some of the clubs that make the list but remember, the participants were largely Spanish-based fans.

While Europe may be home to the best sides in world football, it seems the best fans belong outside of the continent.

Let’s take a look:
