The Weekly Post number 456 of the CIES Football Observatory presents the ten players with the highest estimated transfer values across 66 leagues worldwide (the most important outside the big-5). The rankings were drawn up on the basis of a powerful property statistical model*, explaining over 80% of the price differences observed for about 6,200 paying fee transfers that took place over the last decade.

Stepping stone league to the big-5 per excellence, Portugal’s Primeira Liga brings together the three footballers playing outside the world’s top five competitions with the highest estimated transfer values: António Silva (Benfica, €114m), João Neves (Benfica, €95m) and Gonçalo Inácio (Sporting CP, €87m). Real Madrid's new recruit Endrick (Palmeiras, €80m) tops the list for players active outside Europe, ahead of compatriots Pedro (Flamengo, €42m) and Paulinho (Atlético Mineiro, also €42m).

The following players are the best valued in the other main leagues analysed: Jorrel Hato (€78m) in the Netherlands, Georgiy Sudakov (€52m) in Ukraine, Georginio Rutter (€41m) in the English Championship, Oscar Gloukh (€36m) in Austria, Matthew O'Riley (€31m) in Scotland, Antonio Nusa (€28m) in Belgium, Martin Baturina (€28m) in Croatia, Cristian Medina (€24m) in Argentina, Thiago Almada (€23m) in the MLS and Julián Quiñones (€21m) in Mexico.
