Completely agree with this. The days when a new manager got a couple of years to work things out before expectations are fully applied are long gone. And quite right too. Why should that be acceptable?As for stability, there is very limited evidence that stability breeds success. It’s more often the case that success breeds stability. If I’m good at my job I’ll get a long crack at it. If I’m shit then as soon as that is apparent somebody will be having a word and if I don’t sort it then conversations about an exit strategy for both parties will begin.
Clubs are not run in that way any more. Recruitment, youth policies, contracts, etc. are all decided pretty independently of the manager. He's just there to pick the team and select the tactical approach.
If Puel needs time, the owners quite rightly won't give him it.
