I think the 13 are as follows :-
Wilkerson, Lee,Skinner,Sturgess, Kwashi, Trott, Hogg, Mckimm, Owen,Budge,Evans,Strouts, Hatch.
In addition, Ade has agreed to play on a non contract basis.
Of the others who played for the 1st team last year, the main ones to be resolved are obviously Benno and the Fridge. In addition theres players such as White, Parker, Grace, Gedling, Carter and possibly ex PASE lads ??
Otherwise I guess it will be new signings we pick up between now & the new season - potentially through the preseason friendlies and triallists.
If we get Benno & Fridge to sign, I dont think that will be a bad basis for a squad - defensively it looks as though it would be sound, if we can avoid injuries and suspensions. Midfield wise, perhaps one more strong midfielder, and up front, someone who can score regular goals. But otherwise, should be good enough to get us a better finish than last year & hopefully push us up into upper mid table.
