It's not only about appointments but creating the right positions, enabling them with the correct amount of power, delegating responsibilities properly... A full restructuring in those higher roles. That alone will take time. Then in terms of who we bring in, it's unlikely that every appointment is correct right away. Loads of people to change there, they're bound to make mistakes here and there too.
Setting the structure right with correct responsibilities delegated throughout is what will help us have sustainable success, and not rely on specific individuals just being the very best at their jobs and carrying the team. The goal is having the right setup engrained everywhere that having good people in most of these will be enough for constant improvements and a high floor as a club where we aren't underperforming our spending, and the times when you actually have the best people in charge you are seriously competing for everything available and peaking as a club.
