And if we want better referees it would help if people didn't keep defending the indefensible which happens on a regular basis. This was a penalty as was the one which this same official failed to give when Wilson was taken down at Old Trafford on Sunday.
No, we don't need to defend the indefensible. What we do need to do is look at the mistakes when they occur (and I really don't think this is one) and try to understand why they occurred. One of the reasons is undoubtedly the amount of deception that goes, some of it without doubt practised, which makes the job exponentially harder. It must be really hard to spot some of this as this particular incident has clearly fooled quite a few people.
