The Squawka team has put together a Squawka Value Index, ranking the best-value signings of the 2025 summer transfer window based on their performances in relation to their transfer fees. Our formula shows that Liverpool’s Florian Wirtz has been the league’s worst-value signing so far, with no goals or assists to his name despite a €125m price tag. In contrast, Manchester City’s Rayan Cherki, who joined for a fraction of the price, has been the best-value signing with five assists and a goal in just 399 minutes of Premier League action.
