Since 2013, the CIES Football Observatory has developed a statistical model to assess the transfer value of professional football players on a scientific basis (see notably this paper in the peer review journal Economies). This tool provides access to the estimated value of more than 30,000 players worldwide under a scenario with a contractual duration of at least three years. Precise values according to actual contract durations are available through a paid platform. Any interested institution is kindly invited to contact us.
