Having to bring on a half-fit Done and risk him missing the second leg illustrates the utter failure of NCs squad-building. He's brought in quantity rather than quality and has a huge (by Div. 3 standards) squad and still 'doesn't know my best eleven'. We, unlike any other team, seem to get constant injuries which require a different eleven starting every single game. The chickens have come home to roost.
Tell you what I'd do with Done. Wrap him, Murphy and Basham in cotton wool until August, make sure they're signed up on long contracts and build the team around them next season. The rest can either be squad players or shipped out.
