With a new final phase of the FIFA World Cup to come, women’s football continues its development worldwide. The June’s CIES Football Observatory Monthly Report analyses the composition of squads of the eight clubs having reached the quarter-finals of the 2022/23 UEFA Women’s Champions League.

Footballers under 23 years of age only accounted for 16.8% of minutes played by the UEFA Champions League quarter-finalists. This finding reflects the difficulty for young talents in establishing themselves in the top European clubs. The highest level was recorded for the unfortunate finalists, Wolfsburg (26.3%), which indicates a bright future for the German club.

Almost half of the minutes in the quarter-finalists were played by expatriate footballers. Particularly high levels were recorded for the two English teams present at this stage: Arsenal (83.2%) and Chelsea (74.5%). However, the two finalists, Wolfsburg (30.9%) and Barcelona (35.5%), are at the opposite, which shows that it is still possible to achieve the highest results with a majority of national players.

With 77 expatriates, the double World Cup title holders of the United States are the top exporting country for players active abroad in the ten principal women’s leagues, ahead of Sweden (48 expatriates), Denmark (45) and Canada (44).

Issue number 425 of the Weekly Post presents the top 100 estimated transfer values using the statistical model exclusively developed by the CIES Football Observatory. Manchester City and Premier League top scorer Erling Haaland heads the list with a value of almost €250 million (eventual buy-out clause not considered). Two other footballers under 23 years of age, Vinícius Júnior and Bukayo Saka, who just extended his Arsenal’s contract, complete the podium.

Rumoured close to Real Madrid, Borussia Dortmund’s teenager Jude Bellingham is fourth with an estimated value of €190 million (eventual add-ons included as for all players listed). The Englishman outranks Rodrygo Goes and the FC Barcelona’s duo Pedri González and Pablo Gavi (assuming that the registration of his contract until 2026 will be effective). Jamal Musiala, Phil Foden and Kylian Mbappé (contract with PSG until 2024 only) complete the top 10 list.

The highest estimated values for players from outside the big-5 were recorded for two Portuguese top talents: António Silva (€89 million) and Gonçalo Ramos (€82 million). The SL Benfica’s duo are ahead PSV Eindhoven’s Xavi Simons, FC Porto’s Diogo Costa, Sporting CP’s Gonçalo Inacio and three AFC Ajax players. More information on the statistical model used is available in this scientific paper. Evaluations for more than 30,000 players in 75 leagues around the world are available via a paying platform.

Issue number 424 of the CIES Football Observatory Weekly Post defines the attacking styles of teams from 23 leagues worldwide on the basis of the data on players’ high intensity runs exclusively produced by SkillCorner (>20km/h for at least 0.7 seconds). For each league, clubs are ranked from those whose players perform more in-possession high intensity runs than expected with respect to the minutes of possession to those who perform less.

A positive gap is characteristic of teams tending to go rapidly forward, while a negative gap is typical of teams building-up in a more horizontal way. Most of the dominant teams are in the second category, notably Shakhtar Donetsk (-12.1%), Paris St-Germain (-10.9%) and Manchester City (-8.2%), but RC Lens (+10.1%), Newcastle United (+8.5%) and Borussia Dortmund (+6.0%) show that it is possible to obtain top level results with a more vertical attacking style.

SkillCorner’s pioneering tracking technologies use broadcast and tactical video to deliver physical and contextual data for more than 60 football leagues and competitions across the world. Its standardised physical data allows users to benchmark and track the physical attributes of players, teams and leagues by supporting decision making on scouting, recruitment, player development and team strategy. The data includes a large set of metrics, including the "Count of High Intensity runs" used here.

Issue number 423 of the CIES Football Observatory Weekly Post ranks 60 top division leagues around the world according to the percentage of coaches in place at the start of the 2022/23 season who are no more in charge today. Of the 850 teams analysed, 484 changed coaches during the season, corresponding to a percentage of 56.9%.

The greatest percentages were measured in three leagues from the former Yugoslavia (Bosnia, North Macedonia and Serbia), followed by one from Central America (Costa Rica) and two from Africa (Algeria and Tunisia). At the other end of the scale are India (just one coach replaced in 11), Malta (3 in 14) and Australia (3 in 12). For the big-5, the values range from 55% in the Premier League (11 out of 20) to “only” 35% in Serie A (7 out of 20).

Clubs that changed coach at least once made the first replacement on average after 45.4% of matches, with a negative record of only 24.6% of games led by the coach who started the season in Romania, followed by the United Arab Emirates and Greece. In the big-5, the values stretch from 56.6% in the English Premier League to 35.6% in the Italian Serie A, where clubs changed relatively few coaches but rather quickly.

The 422nd edition of the CIES Football Observatory Weekly Post presents the ranking of the 100 associations with the highest number of expatriate players in 135 leagues worldwide. With a record number of 1,289 expatriates, Brazil tops the list ahead of France (1,033) and Argentina (905). Nigeria, Japan and the United States heads the rankings for the other main confederations.

The Post also presents the number of expatriates by age group, with the French in first place for those aged 23 or under, Brazilians for those aged 23 to 26 and 27 to 30, and Argentinians for those aged over 30. More detailed analyses including changes measured since 2017, with record increases for France and Colombia, are available in the 85th Monthly Report.

Expatriates are defined as footballers playing outside the association where they grew up, which they left following recruitment by a foreign club. This definition makes it possible to isolate sports migration from ordinary one, thus highlighting the flows directly linked to the practice of football. The Migration Atlas presents the main destinations for football migrants of all origins.
