Choosing the right professional sports teams and leagues to sponsor can be challenging, but Euromonitor International's Club Index takes the guesswork out. We rank teams and leagues in a unique fashion, measuring metrics such as team performance, ticket spend and social media reach. We also look at the broader picture - the spending power of fans, generation Z and millennial fan bases and the digital readiness of a market where a team or league is located. Euromonitor's Club Index is a simple and effective way to stay ahead of the game. To learn more about the index and the top 20 ranked clubs for 2019, download our 2019 Club Index.
