Only get rid of your manager if you can get a better one. That includes what the current manager is in terms of squad management and building and confidence on the park as well as success.
We had a great start to last season, due mainly to the enthusiasm of a young squad in following the manager's demands and working as a team.
We've had a poor/mixed start to this season for several reasons: being unable to get the CBs that were wanted, Kranjcar being less than match ready, Barton being allowed too important a role in the team (taking free kicks instead of Tav, slowing down play, etc.), playing 2 DMs to shoehorn certain players in, and several injuries (Waggy, Windass, Rossiter, Crooks, Holt). Some of these were unlucky, some the manager's fault in allowing them to happen.
MW needs to show that he has learned from certain mistakes, for the sake of squad confidence as well as that of the fans.
