They really should look at the problems we encountered in those early years of our growth.
Tough for them right now because they're starting from such a worse position. They almost need players for 6 months that they can wash their hands with after they stay up. However, if they stay up those players are going to cost more, are going to try and rinse them for as much money as possible and may not be ready for the next step. I think Eddie Howe also fits this criteria where I can see them getting rid.
Plus I think the top clubs around Europe have made it a lot harder to copy us and the money is no guarantee if you don't have structure in place, look at United and Everton's spending, Arsenal were similar until recently.
