Not forgetting ticket income and associated commercial income. English teams come off well in this regard, as they generally get high percentage attendances for European games, and they charge the highest ticket prices in Europe, especially in London.
German teams make the most money off of TV revenue though because of thier huge market. I think last year even though Bayern got knocked out in the first group stage they still were in the top 5 in CL revenue.
