Why not look at it being 2 players for every position, yourself and others say we dont have money to spend on "bench" players BUT the top sides dont just have one top player for every position, they have two...also theres 5+ players out next summer and likely even more e.g Howard.
Heres what it looks like based on just long term players...
GK - ?? / ??
LB - Baines / Garbutt
LCB - Jagielka / Galloway
RCB - Stones / Browning
RB - Coleman / ??
DM - Besic / McCarthy
CM - Barkley / Cleverley
AM - ?? / ??
LW - Mirallas / ??
RW - Deulofeu / ??
ST - Lukaku / ??
We add in Austin and a playmaker and with one or two more additions next summer we look pretty strong all over.
