This widget allows users to monitor the evolution of the transfer value of players from the big-5 leagues. The widget also allows users to compare transfer value trends between different footballers. Transfer values are estimated according to an algorithm exclusively developed by the Observatory’s academic team. A research note on the methodology used is available here.

Digital Atlas

The Digital Atlas is an exclusive tool developed by the CIES Football Observatory allowing anyone to compare the squad make-up of teams in 31 top division leagues of UEFA member associations. All indicators are weighted according to minutes played by footballers in domestic league matches since the start of the current season. The definitions are presented within the tool.

Transfer value calculator

This calculator allows anyone to estimate the transfer value of big-5 league players. The calculations are undertaken on the basis of an algorithm created from more than 1,500 fee paying transfers which occurred during the previous five seasons. A more sophisticated version (see research note) is used within the framework of commercial mandates.
