True. But for the infringement in question: "raised foot with contact" slowing down to ascertain contact was necessary. Besides at normal speed it looked like there was contact coz Dier jerked his head like he was shot or something. But the slowdown was realy to confirm he wasn't cheating us and buying the post event reaction by Dier.I know what you’re saying but refs should watch things at the monitor at real time. Slowing things down frame by frame always looks worse to make it look more serious than it actually is.
He wasn't. It was a penalty.
