The approach that all they need is “good footballers” is what has got them into this mess. They need a good director of football, a cohesive vision, a good manager, a good back room team, a good squad of the right size with no dead wood and a good youth system.
All the things that we have, they haven’t. What they have is money so they can turn it around without going down the divisions like city did on the 80s and 90s but this will take them a lot more money and time. And unless they get the big stuff right, ie the people driving this vision, that could be a significant anount of time.
