The club is normally very philosophical about stuff like this and prefer to keep a dignified silence, because getting wound up about things and complaining, especially about the media, tends to be counter productive. This is one instance where I hope the club actually takes a stand. At the very least he should be banned from the stadium and the campus. Personally I would go further and ban talkshite too, and tell them they can stay away for as long as they are giving this cretin the airspace to spew his toxic nonsense.
What next for Collymore? He's beat up a woman, committed public indecency on a regular basis, and now he is laughing at and mocking a professional footballer because he is injured. It's not just unprofessional, it goes beyond that.
