It was a stonewall penalty that should have been given. If Liverpool had gotten away with it we'd all be apoplectic.
It's fine to just say we got away with it. We don't need to bend over backwards or find some previously unseen camera angle that apparently "proves" Rodri didn't do anything wrong, or that Richarlison was offside in the build-up.
We benefited from a lucky bounce for the goal and then benefited from a bizarre VAR cock-up for the non-penalty. It's a bad decision, neutrals will see it as a bad decision. No conspiracy, nothing underhanded, doesn't change the result.
