The edge is there. So how about all those coaches who are coaching nine-to-16-year-olds this weekend promoting Diego Costa and picking out the positives from how he plays? I accept that what he did was a little bit naughty - and while my gut instinct is that he meant to do it, no independent commission could be sure it was his intention, because he was not looking at the victim, and there was no pull-back of the leg and ‘stamp.’ What he does is run on the player rather than stamp.
