CIES ‘Ballon d’Or’: Lamine Yamal again

As was the case last year, on the day of the Ballon d’Or ceremony, the CIES Football Observatory took the liberty of compiling a ranking of the 50 most deserving outfield players over the past year, based on three criteria : performances across eight areas of the game according to this methodology (Impect data), the competitive level of the matches played (method) and the results of those matches.

FC Barcelona’s prodigy Lamine Yamal takes once again the top spot. The Spaniard is ahead of Bayern Munich’s Frenchman Michael Olise and his English teammate Harry Kane. In fourth place, Argentina’s Lionel Messi is the oldest player in the top fifty. He would even have been top had performances not been weighted according to the sporting level of the matches played.

Désiré Doué is fifth, just ahead of Kylian Mbappé and his Paris Saint-Germain teammate Khvicha Kvaratskhelia. Two other FC Barcelona world champions feature in the top 10 (Pedri González and Pau Cubarsí), as does Norway’s Erling Haaland. Last year’s actual winner, France’s Ousmane Dembélé, is, however, only 27th.

Training clubs’ world ranking

As every year in October, the CIES Football Observatory presents a global ranking of the best training clubs* based on the number of players from their academies currently active in 49 top division leagues, the sporting level of the matches in which they participated over the past year, their playing time during the same period, and their age (the younger, the better).

SL Benfica recorded the highest training index (101.3 with 93 footballers trained). Argentina’s River Plate (training index of 95.9 and 94 academy graduates) and Boca Juniors (91.7 and 93 respectively) round out the top three. AFC Ajax is fifth, just behind Vélez Sarsfield and ahead FC Barcelona. The top 10 also includes Portugal’s Sporting CP, Spain’s Real Madrid, Uruguay’s Defensor SC, and Serbia’s Crvena Zvezda.

As for the clubs that have trained the most players currently employed by teams from Europe’s five major leagues, Real Madrid (40 players) outranks FC Barcelona (34), Manchester City (29), Stade Rennais (28), Paris Saint-Germain and AFC Ajax (both 27). Athletic Club (15) and Real Sociedad (14) are the big-5 league clubs with the most academy players in their current squad.

Best clubs to add value to their signings

The 557th CIES Football Observatory Weekly Post presents the rankings of teams worldwide according to the appreciation or depreciation in value of non-academy players signed over the past five years. The calculation considers the balance between transfer fees paid and received for signings who have already been permanently released, and fees paid and current transfer values for those still owned by the club.

Germany’s Eintracht Frankfurt tops the rankings with an appreciation of €527 million: +€293m for players already transferred and +€234m for those still under contract. Real Madrid is right behind with +€526 million : +€27m in “actual” capital gains and +€499m in “virtual” ones, half of which linked to Kylian Mbappé (signed on a free transfer and whose current value exceeds €160 million) and Arda Güler (€30 million vs €125 million).

Three other clubs with sound sports policies and shrewd transfer market strategies round out the top 5: Paris Saint-Germain, SL Benfica and Manchester City. In contrast, Saudi clubs are overrepresented among those whose signings since 2022 have depreciated the most, with Al-Hilal SFC recording the worst balance (-€502 million). The largest depreciation among European clubs was recorded by Manchester United (-€405 million).

*Only clubs whose total transfer spending and income since 2022 exceeds €50 million are in the rankings. Add-ons are included regardless of whether they have been paid or received, as well as the incomes generated through sell-ons.

New educational video: birthplaces of elite footballers

The research team at the CIES Football Observatory is pleased to announce the release of a new educational video unveiling the regions in the five countries hosting Europe’s top leagues (England, Germany, France, France, Italy, and Spain) that develop the most elite football players.

The Île-de-France region is the largest source of talent, not only in absolute terms but also relative to the size of its population. In fact, half of all French players competing in top division leagues around the world were born in this region, even though the latter accounts for only one-fifth of the population.

Other metropolitan areas have a football ecosystem that allows them to develop even more elite players than their population size would suggest : London, Berlin, and Lombardy, in particular. In Spain, three regions stand out : Navarre, Catalonia, and the Basque Country.

Top valued U20 non-big-5 teenagers

The 556th CIES Football Observatory Weekly Post presents the 100 U20 players worldwide who are not yet owned by clubs in the big-5 with the highest transfer value according to our statistical model. Although recently injured, FC Porto’s Polish prodigy Oskar Pietuszewski tops the list with an estimated value of approximately €56 million.

Jorthy Mokio (AFC Ajax) and Mateus Mané (Wolverhampton) round out the top three. The top 10 also includes players from Brazil (Álvaro Montoro), Saudi Arabia (Kader Meïté), Ukraine (Luca Meirelles), and Belgium (Mihajlo Cvetković). No fewer than 24 leagues are represented in the first 100 positions, with a maximum of 13 players from the MLS.

The CIES Football Observatory’s 100% statistical approach not only allows us to evaluate players as they stand today, but also to develop scenarios for estimating likely future developments. Our approach supports football stakeholders for a wide range of applications : transfer negotiations, contract renewals, loans, buy-out clauses, disputes, club sales or acquisitions, financial reporting, credit, insurance, and more.

Game dictating index: Bayern ahead of Barcelona

The 555th CIES Football Observatory Weekly Post ranks teams in 68 leagues around the world based on their willingness and ability to dictate the game, as measured by 27 key performance indicators (Impect data*) based on current season domestic league matches.

The highest game dictating scores were recorded for two of the UEFA Champions League favorites : Bayern Munich and Barcelona. The two-time defending champions, Paris Saint-Germain, are in fifth place, just behind their partner team, the Portuguese side SC Braga, and the outstanding Norwegians of FK Bodø/Glimt.

In the Premier League, Manchester City leads Tottenham and Arsenal. Currently ranked fourth in the table, Brentford is second to last in terms of game dictating index, which reflects a less dominant and more opportunistic style of play : one that can also pay off. In the Spanish Liga, José Mourinho’s Real Madrid is only fifth.

* These include nine defensive indicators reflecting the level of pressure exerted on opponents (pressure index), nine indicators related to build-up play reflecting the level of control over the game (control index), and nine offensive indicators reflecting the level of collective presence in the attacking zone (occupation index).

World’s best U21s outside the big-5: last year performance

The 533rd CIES Football Observatory Weekly Post presents the outfield players who have not yet turned 21 and are playing outside Europe’s big-5 having performed best over the past year, based on a score out of 100 calculated from their statistics across eight game areas (Impect data), the number of official minutes played, and the competitive level of these matches.

Argentine Gianluca Prestianni tops the rankings with a score of 86.5 out of 100. The Benfica right winger, whose transfer value as estimated by our statistical model already exceeds €50 million, is ahead of AZ Alkmaar’s midfielder Kees Smit and Dinamo Kyiv centre forward Matviy Ponomarenko. Fourth-placed Tomás Aranda (Boca Juniors) is the highest-ranked player active outside of Europe, ahead of Leonel Flores (River Plate) and Álvaro Montoro (Botafogo).

Serbia’s Vasilije Kostov (Red Star Belgrade) is the youngest player in the top 10 (18.2 years of age). The American Cavan Sullivan (Philadelphia Union, 16.9), his compatriot Adri Mehmeti (New York Red Bulls, 17.4) and the Mexican Gilberto Mora (Club Tijuana, 17.9) are the youngest talents in the top 100. In total, no fewer than 34 leagues are represented in the first 100 positions, with a maximum of 14 players from the Dutch Eredivisie.

Costliest squads: Liverpool takes the lead

The 552nd CIES Football Observatory Weekly Post ranks the teams worldwide having invested the most on transfer fees (including add-ons, regardless of effective payment) to sign the players currently in their squads. Liverpool FC (€1.226 billion) has moved up three places compared with the same date last year and now tops the table, replacing Chelsea FC.

Six English clubs occupy the top six places, whilst Real Madrid has overtaken Paris Saint-Germain among teams from other countries. The Post also presents the net transfer spending for both the current calendar year and the last ten transfer windows. For 2026, the values stretch from +€207 million for Paris St-Germain to -€287m for Al-Hilal SFC. Over the last five years, from +€337 million for LOSC Lille to -€873m for Al-Hilal SFC again.

In terms of transfer expenditure only, five English clubs are at the top of the table for both 2026 (Manchester City, Tottenham, Aston Villa, Chelsea and Newcastle) and the last five-year period (Chelsea, Manchester City, Tottenham, Liverpool and Manchester United). Brighton & Hove is the only Premier League club with a positive net transfer balance over the last ten transfer windows (+€33m).

Top development clubs worldwide

The first CIES Football Observatory Weekly Post for what promises to be an exciting new season ranks teams from 50 top division leagues around the world according to the percentage of domestic league minutes in 2026 by players who had not yet turned 21 at the time of the matches.

Topping the table with 48.1% of minutes by U21s are Danish side FC Nordsjælland. This is a unique team and project, bringing together players trained locally or at the Right to Dream partner academy in Ghana, as well as other talents spotted at a very young age, and also standing out for its highly technical style of play, its ability to generate great transfer fees and its proven results.

RC Strasbourg ranks second (37.9% of minutes by U21s), whilst the Serbian side FK Partizan rounds up the podium (37.0%). Australia’s Melbourne City is the top-ranked team outside of Europe (5th, 32.9%). The City Group’s side are ahead of the Americans of San Diego FC (30.6%), a club also controlled by the owners of FC Nordsjælland, following a similar strategy both technically and demographically.

New video on migration in football

With another record-breaking transfer window in full swing, footballers are getting ready to pack their bags. Many of them are already playing outside the countries where they grew up, or are preparing for their first experience abroad. Where do these migrant footballers come from? Where are they going? Covering 135 leagues in 88 countries, this video explores the global geography of migration in football.

The analysis highlights the main exporting countries and migration patterns. From the global presence of Brazilian players to the more regional career paths of French and Argentine footballers, the study sheds light on the structure of the international labour market for professional footballers. The Atlas of Migration provides access to even more data.

The CIES Football Observatory website also provides all football fans with other tools enabling them to access exclusive data on team and player demographics, their performance (in collaboration with Impect) and transfer values (in this regard, a paid platform has been developed for industry professionals).

The CIES Football Observatory breaks new ground with Impect

With the 2026 FIFA World Cup in full swing, the CIES Football Observatory is proud to present a new tool, available free of charge, for analysing the characteristics of participating teams and players from the perspective of their technical performance.

For each outfield player fielded for at least 60 minutes, the tool provides an overall performance score out of 100, as well as scores across eight areas of play, based on match data exclusively produced by our partners at Impect, through which comparing players. Detailed explanations can be found in this note.

At team level, we present indices on a scale of 100 relating to teams’ propensity to press opponents, control the game or dominate offensively. The scores for each of these three aspects are constructed from nine indicators, making a total of 27, as explained in this document.

Further information on the outstanding work carried out by Impect is accessible here. We are also available to provide further details on the approach developed.

CIES Football Observatory’s survey findings

The CIES Football Observatory’s research team is pleased to present the results of a survey conducted among our newsletter subscribers on the actions considered necessary in terms of the governance of men’s club soccer. In total, we received 1,424 responses.

For each question asked, we present the proportion of respondents who rated the urgency of taking further action in the relevant area as at least four on a scale of five. The percentages range from 84.9% of respondents calling for measures to combat money laundering through football to just 16.4% who consider it urgent to adopt new rules to deal with excessive goal celebrations.

Negative correlation between temperature and physical performance

The CIES Football Observatory is pleased to present a video analysing the relationship between the distance covered by players during a match and the ambient temperature. Data collected in partnership with SkillCorner from 35 leagues around the world indicates a significant decrease in the distance covered as temperatures rise.

On average, a player covers 10.1 km during 90 minutes of play if the temperature does not exceed 15°C ; this distance decreases by about one kilometre when the temperature rises to 30°C or higher.

Leagues located in the hottest regions are particularly affected by this heat stress, including the Pro League in the United Arab Emirates, the K League in South Korea, the Chinese Super League, La Liga in Spain, and the Brazilian Serie A. With the World Cup underway, MLS data also shows the negative impact of high temperatures on the distances covered.

Top-valued teams: three main favourites

Based on the estimated transfer values* of the selected players, three national teams look like the main favourites to win the 2026 World Cup. England top the ranking with a total squad value of €1.454 billion. They are followed by France (€1.436 billion) and Spain (€1.407 billion). The values of all qualified teams are listed in the 550th Weekly Post of the CIES Football Observatory.

With inflation and a larger number of participating teams, the estimated total value of all squads in the competition reaches €18.1 billion. This is €3.1 billion more than at the 2022 World Cup. As noted last week, the statistical model of the CIES Football Observatory currently values only two players at more than €200 million : Spain’s Lamine Yamal and Norway’s Erling Haaland.

At the other end of the ranking, Iran is the qualified team with the lowest total transfer value, at only €12 million. It is followed by Iraq (€13 million) and Jordan (€15 million). However, strong performances in the competition could still help some players from these teams secure a transfer to much more competitive clubs.
