This is the problem with older fans like yourself, you are stuck in the past. Football is global now and you need to get with the times. Worldwide fans arent always gonna be able to come and watch in london and it doesnt mean they're not fans, but while we're on this topic, after every match arsenal play there is a foreign fan on Arsenal fan tv, who has travelled thousands of miles to watch us at home to burnley. Even our US tour we had fans travelling thousands of miles to watch us play friendlies.
Anyway, back to the point. A worldwide fanbase encompasses many fans who cant always attend. But there are two ways you can measure worldwide support, as these supporters will usually do two things
1) watch their team on TV
2) buy their football top
If celtic have this massive worldwide following why are the viewing figures so poor for their games and why is nobody buying celtic shirts?
If arsenal played a game in lagos or mumbai they would sell out, celtic wouldn't
