Just been browsing the UEFA 2016 club financial report. Some interesting reading if you like figures and graphs.

Palace not directly mentioned much apart from:

Noted for having American owners.

We were 17th in Europe for Broadcast revenue of €104 million(we didn't figure in the overall top 20 total revenue table nor in the top 20 in any other revenue category). This represented 77% of total revenue for us.

We were no.23 in Europe for average yield per spectator per match of 34.6 euro (this surprised me given our ground size). Arsenal were top in Europe at 97.8 euro per match.

For the first time on record, the average wage bill of English Premier League clubs was more than double that of the next highest-paying league (Bundesliga). However, Crystal Palace were not in the top 20 clubs in Europe for wage levels.

The yield figure per spectator doesn't mean we are all racing downstairs at half time and having 2 pies and 3 pints (I wish). More likely it takes into account all the corporate spend, which in Arsenal's case is a huge middle tier full of thousands, spending thousands.
