Was not that long ago Arsenal was one of the more well ran clubs around, how quick things can change. They have pretty much done nothing right for years now.
This is a good point and something we too easily overlook concerning our own progress.
Arsenal, Utd, and Chelsea were well run - independent of how they got their money - for seasons while we were just doing jumble sales.
Under FSG, steadily, slowly, we have become far, far more professional. We get our deals done.
Spurs seem to have problems looming too, and City I don't think are that well run but can just syphon in money for anything they need.
Given Seville's success - comparatively huge success over the last 15 or so years, I imagine they are very well run, and Emery is probably surprised at such a difference considering he's moved to a far bigger club.
Problem is, for all those clubs, it's the people at the top who organize a club's business structure, and if things aren't working, they're the ones who decide what changes to make. Yes, so wonder how that works.
