The year 2025 has been exceptional for several top European clubs. Paris Saint-Germain has clinched the Champions League title, while Liverpool, Bayern Munich, and Barcelona have emerged victorious in their respective leagues. Currently, Mikel Arteta’s Arsenal leads the Premier League, aiming for their first top-flight trophy since 2004. However, with every victory, there are also clubs facing losses, particularly in terms of market value as indicated by <em>Transfermarkt’s</em> assessments. Numerous clubs among the continent's top five leagues have experienced a significant decline in market valuation since the start of the year.

As highlighted in our earlier piece on clubs gaining squad market value in 2025, the most straightforward way for a club to see its market value fluctuate is through player transactions. Outstanding player performances often lead to increases in market value. However, no single player can avert the decline of a club that either decides to sell its top talent or faces external pressures in the transfer market. Consequently, many of the clubs featured in our top 20 list of those with the highest market value losses in 2025 are typically identified as selling clubs during every transfer window.

Notably, when examining the top 20 clubs that generated the most revenue from player sales during the summer transfer window, we find that seven of them are also on today's list. For instance, Nice (€108m in player sales; €37m decline in squad market value), Lille (€110m in sales; -€80m drop), Monaco (€117m in sales; €34m drop), Brighton (€146m in sales; €98m drop), AC Milan (€176m in sales; €62m drop), RB Leipzig (€195m in sales; €159m drop), and most strikingly Bayer Leverkusen, who sold €230m worth of players over the summer yet saw their overall squad market value plummet by €183m, despite investing heavily in new signings.

Nevertheless, not all market value declines in 2025 can be attributed to player sales. For instance, Aston Villa's squad market value has decreased by €56m this year, largely due to several key players seeing their market values decline, such as John McGinn (-€7m), Ian Maatsen (-€7m), Emiliano Martínez (-€9m), Amadou Onana (-€13m), Pau Torres (-€15m), and Ollie Watkins (-€20m). Similarly, Manchester United has experienced a €65m drop in squad market value, largely because stars like Diogo Dalot, Joshua Zirkzee, Lisandro Martínez, and Manuel Ugarte lost a collective €56m in market value this season. The most significant decline, however, has been suffered by Real Sociedad, a Spanish club that has seen its squad value diminish by €174m in 2025, primarily due to nine of their first-team players ranking among the top 25 biggest market value declines in LaLiga since January 1.
