The County fan admitted a charge of using threatening, abusive or insulting words or behaviour, with intent to cause fear of unlawful violence.

That intent to cause fear of unlawful violence was aimed towards McClean, who retaliated; the Police did not bring any charges against McClean for the incident.

Not sure what part you're struggling with here, to be honest. You're letting your obvious dislike for McClean (for some reason) cloud your judgement.
