Some of our fans got it really wrong with Rosenior. A narrative was built that his football was defensive, safety first stuff, that passing out from the back showed a lack of ambition. Walter was supposed to be the antithesis of that. His teams scored more goals and created more chances than anyone, supposedly. He would improve our home form and address the lack of goals because he had the ambition and positivity that Rosenior didn't.
As it turns out, it actually looks very similar. We've turned over a load of players and existing players have had to learn new things which are specific to Walter's game which has set us back a bit, but the principles of playing out from the back are the same, and it's certainly the same that when it goes wrong it is frustrating to watch, and to many fans looks as though we aren't trying to attack.
Walter was hyped to be the solution to a problem that never really existed. He is another modern manager with a particular style which requires patience. We've essentially got what we had before, except he's a less likeable version and he's 2 years further back in the process than Rosenior was by the time he left.
It is what it is. I think sacking him would represent more chaos, and I don't believe his tactics are the problem. I think he understands the game very well and has a plan he knows can work. But it entirely comes down to whether the players like him and can understand him and get on board with him. I doubt any of us know the answer to that.
