It can't solve it, they've breached over three years. Players out of contract is just going to help them in year four.... but fact is, the past 3 years they've breached and will face whatever consequences the EFL decide to dish out.
They had a perfect chance to appease FFP and be within the limits, the last chance was Jan window, sell a player or two and they would have been within limits.
Fact they actually went out and bought another player is a big fuck you to the EFL. Their flagrant flouncing of the rules should be made an example of.
