He'd only be a backup - and if Carey and Ruben aren't injured / suspended for the rest of this season then he probably won't even start a game.

Mansfield also assembled a fairly expensive squad with pedigree at the start of last season, which the overrated Steve Evans failed to get promoted. The overrated David Flitcroft may be about to do the same.
