Arnold sounds like he's going to be a Woodward carbon copy. Another accountant and Glazer lackey with absolutely no footballing pedigree or know-how.
The OP is right, so long as we have the same cabal of money-men steering the ship, we're doomed to be stuck in this "almost" purgatory, where we ironically waste obscene amounts of money trying to remain a profitable Disney-like venture, grossly mismanaging our resources and doomed to be repeating the same mistakes. A new manager won't change diddly squat unless they're given full agency regarding all footballing matters which our board won't be willing to give up.
