I do think it’s a good idea to play in Greece, and I’m not sure that locals have little or no interest. It wouldn’t be broadcast to millions across the globe if there wasn’t global interest. There will be plenty of Greeks in and amongst the English and Spanish. There’s always local interest in previous years.
I’m all for thinking about ways to change the game for the better, I’m not against innovation. In another thread, I agreed with the idea given of a play-off round between Europa Conference winner and Europa League winner, I think that’s a great idea. However, just because I think there are plenty of ideas that can be explored, doesn’t mean the current fifty-year tradition represents “the way that football is going” in a negative direction, and not everything is worthy of a boycott IMHO.
Where something truly awful occurs, I’m the first to call for causing a bit of disruption to get ourselves heard. Like you said, we as fans did that to great and historic effect in stopping the Super League, which everyone is almost unanimously against as an insult to the game. But I would never compare any of the Community Shield, UEFA Super Cup, or Club World Cup… to the European Super League.
