NBA's New York Knicks come in third, followed by Barcelona and Real Madrid. 

Basketball franchises, the Golden State Warriors and LA Lakers, New England Patriots and New York Giants of the NFL and Bayern Munich make up the top 10 teams. 

Despite the COVID-19 pandemic dwindling revenues for these sides, Forbes report that the average value of teams on the list increased by 9.9% to $3.4b in the past 12 months. 

To measure the value and growth of each team Forbes takes 'published valuations for each sport during the past six months, calculated using revenue and operating income adjusted for revenue sharing' and includes 'the economics of each team's arena deal but not the value of the real estate itself.' 

The top 50 list is made up of 26 NFL teams, nine from the NBA, nine football teams and six MLB franchises.
