I’d imagine it’s a fairly small group of people who wouldn’t want to manage Arsenal. Unless you’re already managing a top club like Barca, RM, PSG, Bayern etc where you both earn mega money and have a huge chance of success then why wouldn’t you go for a job like Arsenal?
Get to live in London, the club pay big wages to the manager, good level of prestige at the club, good stadium and facilities and decent funds for player transfers and wages. It’s got to be one of the best jobs in football. There can only be a handful of managers in a better job at any time. Outside of the EPL there’s maybe 10 clubs max that are a more attractive proposition?
