Yeah this 25 man squad thing is a bit of a red herring.
We need 3 or 4 in urgently regardless. As long as we do it properly this time unlike the grossly unprofessional shambles when Sigurdsson was ditched after the window had closed. We have a number of non contributors, whether that be players that arent good enough (De Neve, Henriksson, Tavares, Kargbo) players who will miss the majority of the season (Hedges) or players who have been made redundant by the formation change (Pickering, Ribeiro). As long as we tell players there is a chance that they wont be registered in advance to try and nudge them out, if they choose to stay then thats on them and they take the risk.
