It's a very one-sided account from someone who's had numerous, well-publicised falling outs with John Hughes, but the Tell Him He's Pelé interview with Bobby Barr is a very good account of what it's like to be a mercurial player under his management.
For every disgruntled tricky winger who doesn't want to track back, I'm sure you could find a combative midfielder who'd run through brick walls for Hughes, but there's no doubt he's a divisive figure whose methods live and die by the personalities in his dressing room.
The big advantage, albeit a potentially expensive one, is that the Pars still have January to come. He's got eight weeks to work out who's on board and who's not, and then a window to bring in more of his own men. I wonder how much latitude he's got in that sense. If he wants to flip ten players, is there going to be budget to do that? I suspect he wouldn't have taken the job without those kind of assurances.
