Barney Ronay, speaking the sad truth:
There will be those who feel Walker should have been sent off. In isolation it looked like an outlawed duck of the head, a strict liability offence in freeze frame, never mind the provocation. But then, who really knows? The answer, of course, is: no one knows. There is nothing to know. There is no objective truth, no definitive answer. Other than the fact poorly applied VAR is the same as poor refereeing, only slightly worse because it takes longer. All we really have are opinions, and endless wearying debate.
