He has to stand by his man.
Yes, it's out of the Arsene Wenger Coaching Manual and I understand why he said it.....but we're not fucking blind are we? He could have at least said, "it was perhaps a little rash" or something. That's still putting it extremely mildly but at least acknowledges that Greer did
something wrong. Saying it wasn't 'overly rash' just looks a bit silly really. Is he saying he shouldn't even have been sent off?
