The conspiracy theory talk is so fringe, confined to random corners of the internet, that they don’t need to mitigate against it. This idea rests on 2 assumptions. both that the refs in question are deliberately, or unconsciously, bias against us (and when it comes to sub conscious bias that isn’t particularly far fetched ) AND that the powers that be know this and, wanting Liverpool to lose to City, are deliberating appointing refs to make it harder for us. It’s the 2nd assumption which is mental. Like, why? Why would they want us to lose. It’s bad for the premier league product. So it can’t be that. So maybe it’s that Arab money has bought them off? Believe that if you want, but don’t expect to be taken seriously about much if you do.
