Maybe some players don't like being told what was expected behaviour wise.

If players can't behave then I don't have a problem them moving on.

Do we know anyone's not behaved?

I see that a new revamped World Club Challenge has just been announced and if Hock has the chance to join a team involved in it then I'd guess that is maybe a reason.

As has been said elsewhere we now have a bit of a lovable crackpot owner so anyone signing on must take his unbridled passion for the club and game as whole must be fully understanding of this.
