4. FC Barcelona 

Revenue in 2022-23 Season: €800.1m

Barcelona has experienced a decline since their golden days under Guardiola in the 2000s and early 2010s. Although Lionel Messi played a crucial role during this period, Xavi, a hero from that squad, recently led the team to their first La Liga title in four years. This success helped alleviate the financial struggles they faced. Barcelona’s prestigious name carries significant weight in the world of football, attracting sponsors and broadcasters.
