I think it’s complete naivety on his part to the situation. What he sees is a full stadium making no noise. Does he understand maybe why that is- probably not? You could argue I guess it’s whether you really believe the reason the stadium is quiet is cuz of neutrals /new fan boys or just a lack of support from even legacy/local fans?? His comments aren’t about a lack of support as in numbers, but is more about a lack of noiseI don't think he was involved in setting the prices. He may not even know now. But he will. And he can choose to voice an opinion at that time. Or not.
I suspect he won't though. But if your perspective is that he doesn't know the position the fans are in then surely that's a reason to shut up about the fans and concentrate on speaking about things he does know.
