The evaluation of professional football clubs can be studied and compared by a series of financial and non-financial indicators (including the number of people watching the game, the number of fans worldwide, the number of people watching the game on TV, the performance of the game, etc.). Deloitte's evaluation of football clubs is based on game day revenue (sales of tickets and reception services), broadcasting revenue (domestic leagues, cups and European events) and commercial revenue (revenue from sponsors, peripheral products, stadium tourism and other commercial activities), and ranks on the wealth list on this basis.
