Issue number 218 of the CIES Football Observatory Weekly Post highlights big-5 league players whose transfer value has increased the most during the last six months. Only footballers who did not change team or extend their contract are included in the rankings. In the top positions are three English Premier League players: Mohamed Salah (+€74.7M), Ederson Moraes (+€74.4M) and Leroy Sané (+€63.0M).

The strongest increases for players from the four other major European championships were recorded for Kylian Mbappé (+€54.7M) in the French Ligue 1, Paulinho Bezerra (+€42.4) in the Spanish Liga, Sergej Milinković-Savić (+€40.7M) in the Italian Serie A and Dayot Upamecano (+€35.6M) in the German Bundesliga.

Transfer value estimates are based on the exclusive algorithm developed by the CIES Football Observatory research team. Current figures for all of the big-5 league footballers can be accessed here.
