I don't think we need a massive overhaul in the summer or to spend loads to be honest. What I do think though is there is a lot of dead wood at the club not being used that could get replaced with up and coming hungry kids.
E.g Southampton don't have a massive squad but they have 5-7 players of real quality, now when injurys occur they bring in players like reid, taggart, Gallagher, and ward prowse. Were as if we get injurys we bring in players like distin, alcaraz, mcgeady & hibbert.
As I cant see us getting Europa next year we wont need as big a squad to be honest so id like to see us ship out or at least try to lose the following
McGeady
Hibbo (suppose he can stay for another year)
Ossie (suppose he can stay for another year)
Distin
Howard
Alcaraz
Barry (although I cant see this one happening)
Kone
Gibson (unless he proves 2nd half of season he can be fully fit)
Pienaar
So including some of the younger players to fill in (like ward prowse, taggart etc) our squad would look like this
Gk : Joel (1)
RB: Coleman, Browning (2)
LB: Baines, Oviedo, Garbutt (3)
CB: Jags, Stones, Browning, Galloway (4)
Centre Midfield: McCarthy, Besic, Ledson (3)
Attacking Midfield: Barkley, Naismith (2)
Wingers: Mirallas, Lennon (if signed on perm), Henen (3)
Centre Forward : Lukaku, Naismith (2)
That is 18 players although Garbutt, Browning, Ledson, Galloway & Henen have very little or even no first team experience but what else have we got to lose.
There are obvious positions we need to strengthen in that squad also goal, centre mid maybe and definatly a couple of wingers and if players we wanted to keep chose to leave then they would need to be replaced but it wouldn't break the bank if our scouting is good enough.
That's just me playing football manager though and I very much doubt seeing us taking this step forward
