Up until recent TV deal, Matchday revenue constituted 50% of overall revenue for Arsenal & most clubs. It is now 1/3rd of revenue.
Clubs like Arsenal still rely on it.
If they have to compete with current transfer market, they will eventually raise ticket prices.
And I don’t see what is wrong with that. Look at the table, they have been earning the same revenue from Matchday for last 10 years. Inflation of transfer price needs to be accomodated somewhere.
