On a more serious note, I can't see why plenty of League One clubs wouldn't be interested. Whether they could offer him wages he'd find acceptable is another matter.
Can't see Posh taking him back again, as their policy tends to be to recruit younger players from lower leagues. Gillingham...
Was having a think about possible destinations- ideally it's got to be a lower league club, almost certainly Southern-based, desperate for promotion and who are willing to spend money they don't really have on wages in order to achieve that goal.
Oh, hey!
