Throughout the summer, the CIES Football Observatory will compare the transfer fees paid to sign players under contract with big-5 league clubs with the values estimated by its exclusive econometric model.
Every week, a new edition of the Big-5 Weekly Post will present the comparison between the fee amounts paid and the estimated ones for the latest transfers, as well as the most significant gaps.
So far, the results confirm the accuracy of our model. The first Post comparing transfer fees is available here (issue 39). It includes the 30 players transferred to date for the highest fees. To stay up to date, please provide your email address in the registration form in the bottom left of the Observatory's website homepage.
The statistical model used was built on the basis of paying transfers of big-5 league players from the 2008/09 season onwards. The estimation takes into account a multitude of variables such as players' pitch performances, notably the number of matches and goals, length of contract remaining, age, position and international experience.
More information is presented in the 2013 edition of our Annual Review. The publication is on sale in the online shop of the International Centre for Sports Studies (CIES).
