There are always fluctuations in fortunes either side of the money baseline. If you get lucky and sign Modric and Bale or somehow acquire the Poch team for £100m then you are going to temporarily outperform. But to make that permanent you simply have to maximise income.
Maximising income isn't as simple as charging the highest prices possible, though.
Treating supporters as pure customers ignores various aspects of that relationship.
Sure, the fans aren't going to wholesale stop going and use an alternative outlet.
That's also true of the fans of other clubs, though. You have a limited customer base.
That's looking at things from a purely business perspective, too.
Uli Hoeness had a good take on it when discussing season-ticket prices.
“We could charge more than £104. Let's say we charged £300. We'd get £2m more in income, but what's £2m to us?
“In a transfer discussion you argue about that sum for five minutes. But the difference between £104 and £300 is huge for the fan.
We do not think the fans are like cows, who you milk.”
“Football has got to be for everybody. That's the biggest difference between us and England.”
Keeping the stadium full and having fans turn up early, eat and drink and leave late makes a lot of money.
Having fans happy with the pricing, both of tickets and concessions, means that they'll continue to generate that revenue.
Making it affordable to bring children facilitates this and creates future customers.
Even looking at things incredibly cynically results in a better experience for the fans.
