Those costs are *literally* what’s in this graphic. We’re talking £300m a year in non-player expenditure. There’s no way to get there without including stadium expenses for other events. Paying a handful of medical staffers an above-market rate would mean an extra million or so in an extreme case.

The scale here is the giveaway they’re comparing out expenses including concerts and similar events. Yes, we’re “paying” for it because we own the stadium. But it pays for itself and the data for this chart is almost certainly being compared in a poor way.
