Issue number 494 of the CIES Football Observatory Weekly Post presents the 100 players from outside the big-5 European leagues whose transfer value has risen the most over the last six months. At the top of the list is Porto's Spanish striker Samu Aghehowa, second top scorer in the Portuguese top flight, with an increase of €39 million (from €29.6m to €68.6m).
Palmeiras' new Brazilian full international Estêvão Willian, owned by Chelsea, comes second with an increase of €30 million (from €30m to €60m). Benfica's Spaniard Álvaro Carreras completes the podium (+€28m) ahead of teammate Tomás Araújo (+€25m). Three other players active in Portugal are in the top 10 (Conrad Harder, Geovany Quenda and Roger Fernandes), along with Antoni Milambo (Feyenoord), Jan-Carlo Simić (Anderlecht) and Mika Godts (Ajax).
All estimates have been calculated on the basis of a statistical model developed exclusively by the CIES Football Observatory research team, built on almost 10,000 paid transactions, as detailed in this scientific article. This tool presents the best-valued players per team in 65 leagues worldwide. A paying platform with weekly valuations of over 30,000 players is also available for professionals in the game.
