In terms of following City and supporting them, it doesn't matter. I started supporting City the year we got promoted from League One to the Championship and I went to every home game during the Pearce days. I'll follow them in the Premier League, Champions League, or the National League and below, I don't give a shit. We've had more than a lifetime's worth of success in the last decade so if our time is up then our time is up. No biggie, the cycle comes for us all. And in terms of people thinking our trophies are "legitimate", nobody outside of City thinks they're legit anyway so a guilty or non-guilty verdict changes nothing there. The trophies are for City fans and City fans only; they don't need to be respected by outsiders or blue-tick wankers on Twitter.
The only thing that would bother me is if they stripped us of our titles between 2009 and 2018 (which is when the accusations are focused on) because they were special moments that deserve to be remembered and cherished, and it wouldn't be the same if they were taken away. But I don't think that's going to happen - if we'd been match fixing and paying people to determine the outcomes of games in our favour, that's different, but we're on about misreported revenue here which, while against the rules, is something that happens entirely at a boardroom level and doesn't directly affect the outcome of games. Having more money to spend doesn't equal success, just ask Chelsea and United, so there's not really any way they could make it stick.
And that's if we're even found guilty.
