Issue number 315 of the Weekly Post highlights the big-5 league players whose transfer value has increased the most in November according to the CIES Football Observatory algorithm. The Norwegian prodigy Erling Haaland tops the table for footballers with a transfer valuation of more than €80M: €155M compared to €120M at the end of October (+€35M).

If the reported €75M release clause valid from 2022 really exists, Borussia Dortmund will be certainly tempted to transfer him at a much higher price at the end of the current season. If Erling Haaland continues to score so many goals and perform at such a great level, once the COVID-19 pandemic is over, he could break the €222M transfer fee record currently held by Neymar.

The top increases in November for the other price ranges considered were measured for Giovanni Reyna (+€34M) for players with an estimated value between €40 and €80M, Florian Wirtz (+€16M) for the €20 to €40M category, Nicólas González (+€7M) for footballers valued between €10M and €20 M and Yunus Musah (+€4.5M) for players whose current transfer value is still below €10M. The updated estimated value ranges for all big-5 league players is available here.

Issue number 314 of the CIES Football Observatory Weekly Post presents the ten most represented foreign origins in 126 professional leagues worldwide. The Brazilians represent the biggest contingent of expatriates in 23 championships, followed by the Argentineans (15) and the French (13). The Atlas of migration displays more exclusive data on international transfer networks.

Players who grew up in France notably are the main expatriate workforce in the English Premier League (47 players), the German Bundesliga (36), the Italian Serie A (35) and the Spanish Liga (30). The French represent the most represented foreign origin in eight other associations: Belgium (both 1st and 2nd division), Bulgaria, Turkey, Switzerland, Romania, Qatar, Algeria and Luxembourg.

The most frequented migration route connects Brazil to Portugal: 141 Brazilians play in the top Portuguese division and 106 in the second one. The three other major migratory channels connect neighbouring leagues, with the bigger nation providing workforce to the smaller: from England to the top Welsh division (100 players), from France to Luxembourg (93), as well as from England to the Scottish Premiership (90).

Issue number 313 of the CIES Football Observatory Weekly Post presents the 100 players from the 10 best European leagues who won the highest percentage of aerial defensive duels since the start of the season. Chelsea’s centre-back Kurt Zouma tops the table with 26 aerial duels won out of 27 (96.3%). Berat Djimsiti (Atalanta) and Harry Maguire (Manchester United) complete the podium.

Often criticised by his own supporters, the English international Harry Maguire lost only three defensive aerial duels out of 30. With 90% of defensive aerial duels won, he has the second best ratio in the Premier League ahead of Yerry Mina (Everton), James Tarkowski (Burnley), Jonny Evans (Leicester City) and Tyrone Mings (Aston Villa).

The five youngest footballers in the top 100 are all born in the year 2000: Loïc Badé (RC Lens), Matteo Lovato (Hellas Verona), Arthur Theate (Ostende), Sven Botman (LOSC Lille) and Tommy St. Jago (Utrecht). Only players having won at least 20 defensive aerial duels were included in the rankings elaborated using the data of our partners InStat.

The 59th edition of the CIES Football Observatory Monthly Report presents the findings of the annual census on the demographic characteristics of players from 31 European male top divisions. For 2020, the sample is composed of 12,088 footballers. The study reveals that the pandemic slowed the transfer market and strengthened the gaps in the profile of players according to the sporting and economic level of clubs.

After the COVID-19, the part of debutant players in squads has increased by 1.3% compared to the average for the 2009-2019 period. The growth has been greater in the least competitive leagues (+1.9%) than in the five major European championships (+0.2%). Following the pandemic, teams from the least successful leagues have given a first chance to three times more debutant players than clubs from the best championships, compared to only twice more during the previous decade.

After having fallen progressively between 2009 and 2018, the percentage of club-trained players has increased for the second year running (17.8%). This increase is exclusively related to the greater recourse to footballers from their youth academy by clubs in the least performing leagues (+2.3%). Indeed, within the three top championship groups, the percentage of club-trained footballers has actually diminished (between -0.2% and -0.7%).

The pandemic has also slowed the mobility of players. Squad stabilisation has occurred in all league categories. In 2020, the percentage of footballers recruited during the year has dropped by 2.5% in comparison to 2019. The part of new recruits has fallen to a level not seen since 2012 (40.7%). Confronted with significant revenue shortfalls, most clubs have reduced their activity on the transfer market.

COVID-19 has also reversed the trend when it comes to the international mobility of players. While the percentage of expatriates has grown steadily between 2009 and 2019, it has gone down after the pandemic (41.2%, -0.6%). In this case too, the biggest decrease was recorded for the minor championships (-2.4%), while a slight increase has been observed in the big-5 European leagues (+0.2%).

These findings show that the pandemic has exacerbated the inequalities between clubs throughout Europe. Smaller teams had to lower their ambitions even more than bigger ones. For many of the former, the immediate future presents itself more than ever as a fight for survival. In this extremely tense context, the clubs having built up solid training sectors will pull through better than the others. This holds true from both a sporting and a financial perspective.

Issue number 312 of the Weekly Post presents the exclusive CIES Football Observatory annual rankings of the clubs having trained the most players active in 31 top divisions of UEFA member associations. With 85 footballers trained, the Serbian side FK Partizan tops the table ahead of AFC Ajax (77) and Dinamo Zagreb (71). With respect to big-5 league players, the podium consists of Real Madrid (43), Barcelona (32) and Lyon (31).

In accordance with the UEFA definition, training clubs are those where players have been for at least three seasons between 15 and 21 years of age. For the first time, for each footballer, we also considered the number of domestic league matches played over the last year, the sporting level of clubs where they played them, as well as their age. This allowed us to calculate a weighted score reflecting the training work carried out by clubs also from a qualitative and temporal perspective.

Benfica, Ajax and Barcelona recorded the top weighted scores for the training of players in the 31 European top divisions, while Real Madrid, Barcelona and Paris St-Germain are at the top of the weighted rankings with regard to footballers currently active in the five major European championships.

Alphonso Davies (Bayern Munich) heads the exclusive CIES Football Observatory list of the highest estimated transfer values for big-5 league players born in the 2000s: €180 M. The Champions League winner outranks Jadon Sancho (Borussia Dortmund, €125 M) and Ansu Fati (Barcelona, €123 M). The top 100 is available in issue number 311 of the Weekly Post.

According to the CIES Football Observatory algorithm, among the 12 big-5 league footballers born in the 2000s with an estimated value greater than €50M are four Englishmen (Jadon Sancho, Mason Greenwood, Bukayo Saka, Phil Foden), two Spaniards (Ansu Fati, Ferran Torres), two Brazilians (Rodrygo Goes, Vinícius Júnior), a Canadian (Alphonso Davies), a Norwegian (Erling Haland), a Swede (Dejan Kulusevski) and a Frenchman (Eduardo Camavinga).

Two players born in 2003 figure in the top 100 list: Jude Bellingham (Borussia Dortmund, €44M) and Florian Wirtz (Bayer Leverkusen, €16M). Bellingham heads the rankings for footballers who did not yet play for a national A-team, ahead of Benoît Badiashile (Monaco, €40 M). The latter outranks Ozan Kabak (Schalke 04, €35 M) and Wesley Fofana (Leicester City, €33M) in the table for centre backs.
