Personally I thought the Gyokeres decision was right which maybe proves the point at hand. He won the ball and it wasn't a reckless challenge so for me no penalty was the right call. Totally fair for the ref to give it in real time because you can't see the touch, but once you establish he does touch it and isn't out of control with the tackle it's difficult to justify giving a pen. 99% of tackles everywhere on the pitch have some contact between the players but that doesn't make them all fouls. If you see it the other way though, it kind of goes against your wider point. That was a pen given for a sky 6 side against a non sky 6 side and you believe it should have been a penalty, but actually it got overturned. So the idea that certain clubs always get decisions can't be right can it? Don't get me wrong I do think there's an element of two tier refereeing, but I don't think it's anywhere near as prevalent as some people say and in many cases occam's razor applies - poor refereeing decisions are just poor refereeing decisions, not a conspiracy.
Yes, the decision going against the "sky" club in this instance definitely doesn't fit the tin foil narrative. And I definitely agree that those instances where the sky club benefit get a lot more attention in the wider "non sky" community of fans than the other way round. And sometimes its nothing to do with any of that. Its either a plain mistake by the officials. Or equally, not a mistake, but the "wronged" team and their fans want a straw to clutch at.
Was just using that particular example more of a case of something that I think got classified as subjective, but in my eyes was 100% a penalty. Pope has come out, massively committed. His touch on the ball is effectively meaningless, the ball wasn't won, its still loose and there for Gyokeres to tap in, if he isn't sent sprawling by Pope. I think the vast majority of people who have been on the end of that playing amateur football are expecting a free kick if its outside the box, and a penalty if its inside. And Pope's body language suggested he was bang to rights and couldn't quite believe his luck that it had been overturned!
But I agree with your final comment, I also think 2 tier refereeing is an issue, but fans, managers and players of all clubs should stop using it as their go to recourse when things don't go their way. It totally devalues the genuine grievances and instances for genuine questioning.
