What Moyes should do now (if he has the full backing of the board, and I believe he has) is identify the troublemakers in the dressing room (RIO) and just show em the door. Even if it's RVP, Evra (RIO) or any other big personality. Fergie wasn't afraid to ship out big names. As Moyes tries to copy SAF so relentlessly, he shouldn't be as well.
Whoever can't or won't do what Moyes requires (in b4 crosses, ha ha ha), or isn't "inspired" by him should leave, simple as that.
Things can't get any worse, it's the perfect time for Moyes to stamp authority.
Or he can just continue to blame luck and every other thing til he gets the sack a year or two later. His choice really.
