The problem being is that those players are key to the six clubs - they are expensive assets. That's why they either need to stand up and be counted ( maybe slapping in transfer requests ) or be banned. If the players see their career fading away overnight they are more likely to speak up.
Good as an interim holding statement before the meeting of the remaining 14 today - calm and open to discussion. I'm hoping the statement from the collective 14 will be far more hard hitting and threatening.
