The first CIES Football Observatory Weekly Post of the 2018/19 season assesses from an economic perspective paid transfers having taken place during last summer. It highlights that Thibault Courtois went to Real Madrid for a much lower amount than the estimated fair price (-€23 M). Conversely, Chelsea FC paid over the odds to recruit his substitute: Kepa Arrizabalaga (+€45 M).
The fair price corresponds to the average between the estimated cost for the most likely buyer before the transfer and the current transfer value. Both figures were calculated using the exclusive CIES Football Observatory algorithm. The correlation between fees estimated and reported for players transferred for money from big-5 league teams during last transfer window was 75%.
Rodri Hernández, Bryan Cristante, Fabinho Tavares and Clément Lenglet are alongside Thibaut Courtois in the top five for the best operations from an engaging club perspective. For Rodri and Lenglet, the existence of a release clause helped recruiting teams to sign them at a favourable price.
