Guaranteed titles and regular CL challenges, don't mean much if you're a few bad results away from being sacked. They have no stability for managers, in most cases their dressing room is poison, there's always key players who go against the grain and cause issues by leaking whatever issues are transpiring
The last manager who lasted there more than 2 years, was Guardiola [and he left after 3]. In fact, the only manager who has gone more than 3 years managing them, was Hitzfeld [from 98 to 04]. They've changed managers 15 times since then.
In my view, the Bayern job will be easier to get, whenever he wants it, while we are more of a rare opportunity because more often than not, we give managers time more so than any other club .
I seriously doubt it.
