For me we can lose the likes of Sibbitt, Walker, Joseph etc. We have managed most of this season without them. I think that the squad could be streamlined slightly to have a little more quality. Rather than having a squad of 33+ first team players, we should look at having 23-25 quality players.
Injuries should be covered by the youngsters rather than journeymen at the back end of their careers. We have a talented academy team, and although they are very young, the odd game here and there to cover injuries will only do them good.
I know that all of this is academic if we don't sort the finances out, but presuming that we would have a similar budget for playing staff I feel that we'd be better placed by giving young players improved longer contracts rather that overfilling the squad, and spending a little more per head on a few less squad men.
