It was around the £22m mark but that's not the point. United haven't spent £20m in years. City rarely spend less than £20m and (damn near) all their spending has happened over the past 5 years. Buying a title is what happens in a small period of time. The fact that United's squad, amassed over a decade or more, is more expensive, completely misses what the meaning of 'buying' the title means. I suspect those claiming it know fine well that they're missing the point but are hoping their point will stand. It doesn't.
