It's not that I think it wasn't a penalty. Just a classic one that makes you wonder about level playing fields and such.
And not because of corruption or grand schemes involving Keir Starmer's toenail clipper. Just that refs are cops, and love sucking up.
Doesn't this particular conspiracy theory rather assume that Arsenal are someone that UEFA give the tiniest toss about?
I can't think of a single reason why the shadowy UEFA suits would lose a single moment of sleep over trying to get Arsenal to lose in the final rather than the marginally bigger, more prestigious team that they're playing.
