Modern football clubs in Europe are spending a lot of money on transferring players instead of developing their own talent. The study looked at how much money top clubs in England, Spain, Italy, France, and Germany spent on player transfers in 2019. They found that English clubs spent the most, followed by Spanish and Italian clubs. The main sources of income for these clubs are TV rights, advertising, and ticket sales. UEFA and FIFA monitor the financial activities of these clubs to ensure they follow fair play rules.
