United generate €122 million in matchday income. Compared to our (approx. - current conversion) €23 million. Certainly there will always be a gap until we can sell out 76,000 seats and are in Europe, etc. But the point is - a new stadium is vital.
FFS, that's quite a gap. Certainly more matches helps in no small measure, but I'm certainly also underestimating the potential revenue of a new stadium.
