Whoever is manager after Wenger we risk having the same problem again if they are allowed the same autonomy as Wenger
Wenger is far from being unique in his flaws, the problem is that he is allowed too much responsibility. The next manager must first of all be totally beholden to Ivan Gazidis not the majority shareholder.

They must be part of a large coaching team, they decide who they want to buy but it should be the board not the manager who worries about how much is spent and the resale value, if the manager wants to award a player a new contract it should be a negotiation team working with the board that determines what contract that player is deserving of.

Statistically we know that most of the time it's the money spent rather than who the manager is that determines sucesss.

It's the biggest factor, our frustration with Wenger aside we know full well that Pellegrini has not been instrumental in what city have won. Mourinho is a factor at Chelsea but only because the instability at the club makes success difficult without someone who is a specialist at walking in and delivering instant short term success.

But Arsenal has become Wengers personal fiefdom when he should be a club servant.
