I've just done a quick head count and i think we need 6 as an absolute minimum
GK Wilson Moore
RWB New signing, cover Burroughs, Latibeaudiere?, Eccles
CB Mcfadz, New signing (Latibeaudiere? ) New signing (Mcnally?) New signing (permanent) New signing (Doyle type loan?)
LWB Bidwell Da Silva
CM Kelly, Sheaf, Eccles Hamer
AM Tatsu, Palmer, Allen, O'Hare
ST Simms Godden New signing
As a minimum we need rwb, 4 cbs(not counting Latibeaudiere as signed, so three plus him if it's a done deal) and a striker.
Then you are looking at replacing players such as Moore and Bidwell if they leave.
And really we need to be upgrading players like Godden, Allen, Palmer, Kelly if we want to be challenging for the play offs on a regular basis.
