Financial Fair Play (FFP) is a set of regulations established by UEFA to promote financial stability in professional football clubs. The main goal is to ensure that clubs do not spend more money than they earn, preventing excessive debt and promoting responsible financial management. Under FFP rules, clubs must balance their spending with their income over a specified period. If a club fails to comply, it may face penalties, including fines or restrictions on player transfers. This system aims to create a level playing field, encouraging competition and sustainability within the sport.
