We can keep sacking the managers but until we sign players for a specific way of playing the game, we'll keep struggling. This current debacle is mainly due to the naivety of Jason Wilcox. I don't even know the type of direction he's implementing on the football side of the club. It's pretty bad if we look at it from a tactical and strategic pov as far as implementing a system of play is concerned.
Of course it's absolutely a bit odd to see the CEO appoint the head coach rather than the DoF (Ashworth) whose remit it should've been to head the football structure at the club. But they didn't stop there, they also selected the chief scout for Ashworth and also gave him no say as far as who was to assist him as the DoF, hence Wilcox was brought in by Berrarda as well. I think from what The Athletic have reported, it seems there was a power struggle between Berrarda/Wilcox vs Ashworth and Ratcliffe had no choice but to side with Berrarda due to his role as the CEO.
Mistakes can happen when hiring a head coach and you absolutely shouldn't look to sack everyone from the upper-management. But I would say that right now if Ratcliffe made a decision to bring in a new director of football, I would be in favour of that because for me the recruitment has been a mixed bag, without any thought process on how the team was going to develop themselves as far as playing a more dominant brand of football. How the DoF didn't even notice our biggest issues in two consecutive transfer windows is quite shocking and it's no surprise that we have the same problems we had several years ago.
Arteta and Klopp recruited players for a specific way of playing the game. Both managers went for players with pace, power, athleticism and technical quality in the first two lines of their respective teams. I don’t know why we don't seem to understand this.
