They have huge global support and still one of the biggest worldwide 'brands'
However their success does not match this, think of the other global brand clubs they compete with - barca, man utd, Chelsea, real Madrid...all still winning titles
I think this is why so many of their fans are so weird, they cannot cope with being this massive brand and not winning anything
The champs league win 12 years ago made it worse, they gained more glory fans and the current fans were fooled into believing this would be a regular thing...when it was a one off
