I'm not saying he deserves a premier league job, I'm trying to understand what him potentially doing well at league one level, does for his chances at United. You do know that Di Canio and Ince started out at so called "smaller teams" right? Di Matteo is also a champions league winner, for the record.
If the premier league has a sacking culture, what do you think league one has? There's no regard for reputations there, it's even worse. What chance has he got to imprint a style or whatever, when he's immediately under pressure to get results? Even more so because of who he is.
