Marco will be here to stay, if we sack him anytime soon we really are turning into Watford / Villa, wasting millions sacking managers.
We had no money in the Moyes era but you knew what we stood for, there was a backbone to the team, either Carsley, Gravesen or Cahill, over the years someone who would stand up. That fell apart under Martinez and has never recovered. The board have a lot to answer for, they sacked Koeman without a plan, Marco was flavour of the month and went all out but failed and unlike West Ham who handed Moyes an end of season deal, offered BFS a multi year deal then had to pay him off for a manager who has achieved nothing and never sticks about. Not convinced at all by Silva but having a revolving door of managers won't do the club any good.
