Issue number 243 of the CIES Football Observatory Weekly Post presents the top 20 tables for big-5 league players whose transfer values have increased the most during the last three months both in absolute and relative terms. At the head of the two rankings is the fresh English full international and Borussia Dortmund player Jadon Sancho : +€78 million and +806%.

Apart from Sancho, four players have seen their transfer value increase by more than €30M: João Cancelo (Juventus), Andrew Robertson (Liverpool), Richarlison (Everton) and Thilo Kehrer (Paris St-Germain). Many hot prospects are in the top 20 list of players whose value has risen the most in relative terms. The highest figures per league were recorded for Jadon Sancho in Germany, Moise Kean in Italy, Stanley N’Soki in France, Isaac Success in England and Júnior Firpo in Spain.

This analysis was performed using the exclusive CIES Football Observatory algorithm. A detailed explanation of the approach developed is available in this research note. The transfer value of all big-5 league players is freely accessible on the CIES Football Observatory website. The figures published refer to the estimated price for the most likely recruiting club. Moreover, a calculator was developed to allow users assessing the transfer value of players worldwide. However, this tool only provides rough estimates. Deeper analysis is available on demand.
