The 520th CIES Football Observatory Weekly Post presents the players who have not yet celebrated their 20th birthday with the highest transfer value according to our statistical model. In four cases, the estimate exceeds €100 million (with add-ons and for 100% of rights) : Lamine Yamal (€350 million), Estêvão Willian (€118 million), Pau Cubarsí (€113 million) and Franco Mastantuono (€102 million).

Issue number 519 of the CIES Football Observatory Weekly Post presents the 50 countries in the world whose clubs have generated the most revenue over the last ten years from the international transfer of players trained in their country (including add-ons and sell-ons). France is clearly in the lead with €3.98 billion, an average of almost €400 million per year.

As every year, the CIES Football Observatory has identified the clubs having trained the players currently active in 49 leagues around the world to establish a ranking of the clubs with the best academies. The 518th Weekly Post presents the top 100 according to a training index taking into account the number of players trained, the level of the clubs they played for last year and the official game minutes played over the same period.

Thanks to the collaboration with Impect, the CIES Football Observatory has developed performance indices on a 100 basis in eight areas of play. This Weekly Post presents the 50 outfield footballers with the highest values in each domain for the last six-month domestic league games, with each player appearing only in the ranking for the area in which they scored highest.

The 516th CIES Football Observatory Weekly Post highlights the clubs whose estimated transfer value of players owned has changed the most, positively or negatively, over the past year.

The 515th CIES Football Observatory Weekly Post ranks teams from 69 leagues around the world according to the average age of line-ups fielded in the current domestic league season. Not including B-teams, the lowest value overall was recorded for Latvian side FK Metta (20.96 years), while the highest was measured for Saudi Arabia’s Khaleej FC (31.62 years).
