They should be, what if they don't go up? My understanding is (and I could be wrong) that under an embargo, they cannot buy or SELL platers until their accounts are back in order.
That would mean the only way they can bring them back in order is by releasing players. If they are unwilling to do this they could be frozen out of any transfers for years.
Players would be wise to consider this before signing as well, as they may just be stuck at that club until the end of their contract.
That's how I see it anyway.
I think the situation is that they can sell players but can't sign anyone or renew an existing contract if a player becomes out of contract until they have brought the club back within the FFP criteria.
