The young French prodigy Kylian Mbappé heads the CIES Football Observatory table for the U21 big-5 league players with the highest estimated transfer values. The Paris Saint-Germain striker outranks Dele Alli (Tottenham Hotspur) and Leroy Sané (Manchester City). The top 100 list is available in the issue number 206 of the Weekly Post.

According to the exclusive CIES Football Observatory’s algorithm, during the last three months, the transfer value of Kylian Mbappé has increased from €133.8 M to €182.8 M (+37%). This allowed him to outrank Dele Alli, whose transfer value remained stable at around €180 M. Ousmane Dembélé (Barcelona), Timo Werner (RB Leipzig) and Gianluigi Donnarumma (Milan) top the rankings in their respective leagues.

The estimated transfer values for all big-5 league players are available in the ratings module of the CIES Football Observatory’s website. This widget allows you comparing transfer value trends. Media and clubs interested in this tool or in our services can contact us.
