Not necessarily. I agree that you can't be changing systems every year. That messes things up a lot. But if you change every 3-4 years, that could work too. Say Conte leaves after 2 years. I would expect the players he brought in specifically for his system to have done well enough that we can sell them at a good fee and have the funds to get in new players that will fit the new manager's system. The important thing is to get the right players. You do that and the players will look good and be sellable allowing you to get the new profile of player you need for your new system. And of course about 60-70% will fit both systems, so it's never going to be wholesale turnover. Just a healthy 20-30%.Continuity. Whenever Conte leaves, we need to appoint a manager that's experienced with his style and the next evolution of it. That way we don't have a squad full of square pegs for a board full of round holes. That's how you fall apart like United have, they're forever switching managers and systems and utterly wasting all their expensive signings. Continuity is why Ferguson and Wenger were so successful for so long. Just not having to reinvent the wheel every 3 years puts you a leg up on 3/4s of the league.
