Monthly Report 29

Demographic study of European football (2009-2017)

This Monthly Report analyses the evolution of the demographics of the European football players’ labour market since 2009. The study covers the thematics of training (club-trained players), internationalisation (expatriate footballers) and stability (players recruited during the year). The statistical indicators that have been reviewed allow to compare policies pursued by clubs in composing their squads on both a temporal and spatial level.

Performance and playing styles in 35 European football leagues

The 28th edition of our Monthly Report compares 35 national competitions across Europe using the database made available by the InStat company.

Transfer market analysis: tracking the money (2010-2017)

The study of the transfer market constitutes one of the key areas of research of the CIES Football Observatory. This report analyses the paying fee transfers having taken place since 2010 which involved teams of the five major European championships: the English Premier League, the Spanish Liga, the German Bundesliga, the Italian Serie A and the French Ligue 1.

Women’s football analysis : a comparison of five major leagues


Women’s football is currently undergoing a welcome development. At the elite level, the process of professionalisation is well underway in several countries worldwide. Following in the footsteps of the CIES Football Observatory studies, this report analyses the composition of squads in five of the world’s most developed leagues (Frauen Bundesliga, Damallsvenskan, Division 1 féminine, Women’s Super League and National Women’s Soccer League). The study investigates the criteria of age, origin and international status of players.

In total, 174 national associations have at least one representative active abroad in a club included in the sample.

The demographic stock exchange: a new tool at the service of football

The 24th edition of the CIES Football Observatory Monthly Report studies the demographic evolution of the big-5 European leagues since the 2009/10 season. The analysis focuses on the percentages of domestic league minutes played by four categories of players: club-trained, under 21s, expatriates and recent arrivals.

Monthly Report 23

Strategic analysis of a professional league: Switzerland as a case study


The studies carried out since 2005 by the CIES Football Observatory are not only geared towards the general public, but are also useful to actors in the game. The 23rd Monthly Report illustrates an approach that allows a professional football league to analyse on an objective basis its international positioning and influence in a positive way the strategic choices of the clubs that compose it. The example chosen is that of the Swiss Football League.

Monthly Report 22

Goalkeepers: what kind of specifics?


Goalkeepers occupy a particular status in football teams. The qualities needed to play in this position are very different from those required from outfield footballers. Issue number 22 of the CIES Football Observatory Monthly Report compares goalkeeper characteristics with those of footballers playing in other positions. More particularly, the study examines the criteria of height, age, origin and mobility.

Monthly Report 21

Who will be champion? A predictive analysis of performance

The 21st Monthly Report of the CIES Football Observatory presents a predictive analysis of the number of points that each big-5 league club will obtain at the end of the season. In order to do this, we use a multivariate statistical model built on the basis of results observed from the 2011/12 season onwards. The model takes into account the offensive and defensive performances of big-5 league teams until the 31st December of each season, as well as the level of their grip on the game.

Monthly Report 20

The international mobility of minors in football


Issue number 20 of the CIES Football Observatory Monthly Report investigates the international mobility of minors in football. It notably reveals that the number footballers who left their country before to turn 18 playing in 31 top division leagues of UEFA member associations has reached a new record high in 2016. English clubs are by far the most active in the international recruitment of minors.

Monthly Report 19

Demographic study of football in Europe


The 19th Monthly Report presents the main findings of the annual census carried out since 2009 by the CIES Football Observatory on the profile of players active in 31 top division leagues of UEFA member associations. The study shows that the presence of club-trained players continues to decrease, while that of expatriates is on the increase. The greater international mobility of players brings with it a growing instability in squads.

Monthly Report 18

Recruitment strategies throughout Europe


The 18th Monthly Report of the CIES Football Observatory analyses the recruitment strategies followed by clubs from the five major European championships. The Report shows that the most competitive teams pursue a transfer strategy based on quality. They focus on the fee paying transfer of young players with high potential and hold on to those who perform best over the long term. In addition, the wealthiest teams tend to recruit more internationally than those with lesser means at their disposal.
