you do have to question these 2 players then. Took action against their last club due to non payment to sit around waiting to be signed by another club that they cant sign for due to financial irregularities......sorry but isn't this out of the frying pan into the fire ?? If it was me i would be touting my trade with another club !
They can sign, they just can't yet be registered to play but yes totally out of the frying pan and into the fire.
I would imagine their agents have negotiated a clause whereby they can serve 7 days' notice if they haven't been registered.
