You might recall that last season, as the post-Moyes fallout fell out, there was a brief kerfuffle about chips, and the lack of same. Apparently United's players were in the habit of getting together for a few the night before a game (low-fat ones, of course), and Moyes' decision to end this tradition demonstrated that he simply wasn't up for the job, that he didn't understand top flight management, that he really hated Rio Ferdinand.
Yes, I did ban chips. It was because a couple of players were overweight and I didn't think chips were good for their diet.
You can, of course, reach you own conclusions on which players Moyes was worried about. Still, it's all very well banning chips before the game. If he'd banned them during the game, then Danny Welbeck might have scored past Manuel Neuer, and who knows where we'd be now?
