Not sure you understand, you cannot employ somebody into a post that somebody else is employed in already. If Gus is still in place albeit suspended, we cannot just simply get Redknapp in. I think it may be unlawful. Imagine if you had been suspended from your job. You would be pissed if your employer got a replacement in to do your duties would you not?
No, it's you that doesn't understand. Nothing at all to stop the employer taking on a 'temporary' replacement.
