I see your point, but that is unrealistic at the moment, given how much it would cost. At a bare minimum (to have 2 players for each position) we need to sign a GK, CB, RCB, RWB and RCM for next season. The keeper (Henderson or otherwise) will be first team, and maybe the RCM if Lunny keeps playing silly buggers with his contract, but who could we sign who would improve our defence (the second best in the PL) while also being affordable? The best we could do is bring in some young, improving players and try and mould them into eventual replacements.
