Its a forum and all about opinions, however I don't agree he is a charlatan or technically clueless. Clearly his team have been underperforming for some time, and the entertainment level has fallen off.
But it is worth considering we are bedding in half a new team here, when we consider the 3 January signings got a few weeks and Ojo and Bryson have been injured for much of the time since we signed them.
The assembled squad looks as strong as any group we have had for a generation, he needs to be given a opportunity to work with the squad, and demonstrate our new football philosophy. We seem to be operating at a different level as far a player recruitment goes, and that brings additional expectation and pressure for the manager.
However you may get your wish as its unlikely Dave Cormack will view anything other than a close 3rd place as the minimum acceptable performance level, if or when that looks unachievable DC will likely make the change.
