Issue 406 of the CIES Football Observatory’s Weekly Post presents the 50 clubs that spent the most on the player market during the current and last summer’s transfer windows. Chelsea crushes the competition with €555 million invested (including add-ons) to acquire 15 footballers. This is more than double the amount spent by the second biggest spender: Manchester United (€272 million for 7 players).

West Ham United, Nottingham Forest and Wolverhampton Wanderers complete an all-English top five. All twenty Premier League teams but Leicester City (51st), feature in the top 50, reflecting the increasingly obvious economic dominance of the English top flight. Barcelona is ahead of Paris St-Germain among non-Premier League teams, AFC Ajax tops the table for clubs outside of the big-5, while Flamengo is the only non-European team in the top 50.

Per league, the English top division is far above any other championship with a staggering €3.19 billion total fee expenditure (add-ons included). This is almost four times more than the amount invested by the teams in the second biggest spending league: the Italian Serie A (€826 m). The French Ligue 1 (€726 m) completes the podium ahead of the Spanish Liga (€708 m) and the German Bundesliga (€689 m). The sixth ranked competition, the Dutch Eredivisie, is at a much lower level (€228 m).

The highest proportions were measured for the Slovakians of MŠK Žilina in total (73.3% of minutes by 16 players trained) and Athletic Club in the big-5 (56.6%; 13).

Club-trained footballers played a majority of minutes for only one other team in the five major leagues: Olympique Lyonnais (52.2%; 11 "trained"). Real Sociedad rounds out the podium for the big-5 (40.2%). Chelsea and Brighton & Hove top the list in the English Premier League (26.9%), SC Freiburg in the German Bundesliga (31.0%), AS Roma in Italian Serie A (17.8%), as well as SL Benfica in the Portuguese Primeira Liga (25.8%).

Thirty-three teams are at the bottom of the ranking with no player trained fielded in current season’s domestic league matches. Among them are 11 big-5 league clubs: one from Ligue 1 (Olympique de Marseille), one from the Premier League (Brentford FC), one from the Bundesliga (Union Berlin), three from the Liga (Cádiz, Getafe and Almería), and five from Serie A (Bologna, Lecce, Udinese, Cremonese and Salernitana).

Issue number 404 of the CIES Football Observatory Weekly Post presents sixty players whose contracts end next June with the highest Impact Score in their age group. The French Evan N’Dicka (Eintracht Frankfurt) tops the list among footballers who have not yet turned 23, the Spaniard Marco Asensio (Real Madrid) for those aged between 24 and 26, as well as Adrien Rabiot (Juventus) for players between 27 and 30 years of age.

While these players can be signed without the payment of a transfer fee in six months’ time, they already represent excellent opportunities for clubs wanting to get ahead of the competition. The highest transfer value among the footballers listed was recorded for Youri Tielemans (Leceister City, €30.8m), ahead of Milan Skriniar (Inter, €30.3m), Marco Asensio (Real Madrid, €21.9m), Youssoufa Moukoko (Borussia Dortmund, €20.3m) and Adrien Rabiot (Juventus, €19.5m).

The Impact Score is a metric that is perfectly comparable between all footballers regardless of their technical characteristics, taking into account the sporting level of matches played during the last year, minutes played in official games, as well as playing performances (InStat data). This tool available for free presents the Impact Score value for players in more than 70 leagues worldwide. Under contract only until June 2023 too, Luka Modric is among the six players scoring the highest (100).
