I am not a fan of N'Zogbia. He runs like headless chicken, and his precision is well Montero-esque at best. Technically very raw, and apart from enthusiams I don't see him being a good player.
Newcastle IMO is just very very badly run team, with knee-jerk reaction when teams get wrong. I feel it is more than just a manager. A chairman with a record of signing Luque, Owen, Boumsong, Duff, Emre, Martins for an amount they have - well I pity the fans. If Moggi was doing that he would have been fired next day. Of course, chairman can't fire himself (Signora Moratti too), unluckily for the Newcastle fans, their chairman isnt as rich as Moratti to throw more money at the problem.
