This new Monthly Report analyses the composition of teams participating in the five of the most developed women’s professional leagues worldwide: four European leagues (Germany, Sweden, France and England), as well as the National Women’s Soccer League in the United States. It reveals that the age of players increases, international mobility grows and the concentration of the best footballers within a limited number of clubs independently of their origin pursues its course.

The average age of players on the pitch has risen from 25.1 years of age in 2017 to 25.5 in 2019. The German Bundesliga is the only championship in which the average age on the pitch has fallen over the last three years. It is now the league fielding the youngest players among those covered by the study: 24.7 years of age (-0.8 since 2017). At the opposite end is the United States National Women’s Soccer League: 27.5 years of age (+1.3 years since 2017).

The percentage of minutes played by expatriates has increased for the third year running reaching a figure of 32.4% (+4.4% in comparison to 2017). The most notable increase was recorded in England (+7.5%), where more and more clubs invest in women’s football through reproducing the same mechanisms already observed in the men’s game. The total number of expatriates in the leagues covered increases year by year: from 300 in 2017, the figure reached 348 in 2018 and 379 in 2019.

Numerous teams play with a majority of footballers with international status. The percentage of minutes played by the latter reaches 99.0% at Bayern Munich and 98.8% at Arsenal. It is greater than 90% in three other teams: Wolfsburg, Manchester City, as well as at the multiple European champions Olympique Lyonnais (94.2%).

Though encouraging, the evolution noted shows the importance of reflecting on regulatory mechanisms to limit the negative effects due to market logics already observed in the men’s game such as, among others, the speculation on young players, the concentration of resources and competitive imbalance.

What is the percentage of points won by champions in the five major European leagues? Issue number 264 of the CIES Football Observatory Weekly Post answers this question for the last twenty seasons. The analysis reveals a progressive increase in the percentage of points achieved by champions.

On average, big-5 league champions obtained 69.9% of points for the five-season period between 1999/2000 and 2003/2004. This percentage went up to 73.9% during the following lustrum, to 77.7% between 2010 and 2014, and again up to 80.5% for the last five seasons. This reflects an ongoing trend towards competitive imbalance.

The record figure overall was registered for Juventus in 2013/14: 89.5% of points. At the other extreme is Olympique Lyonnais in 2002/03: 59.6%. All 2018/19 big-5 league champions achieved at least three quarters of points: from 86.0% for Manchester City (second highest score in the English Premier League history) to 76.3% for Barcelona.

Issue number 263 of the CIES Football Observatory Weekly Post analyses the average length of passes by teams from 35 European domestic leagues. The study highlights big discrepancies in playing styles. There are almost 8 meters difference between the teams that executed the longest and shortest passes: Rotherham United (23.42m) and Paris St-Germain (15.85m). 

Many very competitive teams are in the top 25 of the rankings for the shortest passes, including Champions League semi-finalists FC Barcelona (2nd) and AFC Ajax (5th), as well as Europa League finalist Chelsea FC (4th). The vast majority of teams executing the longest passes are in the bottom-half of the table in their respective leagues. Getafe CF is the exception that confirms the rule. 

The analysis per league also reveals the persistence of cultural differences in the approach of the game. Teams from the Scottish Premier League (21.08m) and the English Championship (20.58m) execute on average the longest passes. At the opposite end of the table, we find the French Ligue 1 and the Finnish Veikkausliiga (18.89m in both cases). Data comes from InStat.

For the third year, the CIES Football Observatory analyses the presence of expatriate players in 147 leagues from 98 national associations. Brazil is clearly at the top of the rankings for countries exporting the most footballers (1,330 players), ahead of France (867) and Argentina (820). Alone, these countries export almost a quarter of footballers (22.5%). Overall, the number of expatriates increased by 5.0% compared to 2018.

During last year, the number of expatriates has increased for each of the three principle exporting countries: Brazil (+64 players, +4.8%), France (+37 players, +4.3%) and Argentina (+57 players, +7.0%). The number of Spaniards abroad has also strongly increased (+61 players, +14.3%). This is the second biggest increase in absolute terms after that of the Brazilians.

The most frequented migratory route originates from Brazil and ends in Portugal (261 players). The migration of Argentinians to Chili (116 players) is the second principle axis. Two migratory channels departing from England also involve many footballers: the first ends up in Scotland (113 players), while the second leads to Wales (92 players).

England and Italy are the chief importing countries of footballers. The professional clubs of these countries employ 728 and 636 expatriate players respectively. Without taking into account the 139 citizens of the other UK nations present in England, it is thus in Italy that the greatest number of players imported from abroad are to be found.

The CIES Football Observatory research team is also proud to disclose the brand new Atlas of Migration mapping the international flows of footballers.

Issue number 262 of the CIES Football Observatory Weekly Post presents the three best and worst teams per league in terms of points that they should have achieved according to their pitch production. Virtual points were projected according to a statistical model including shots taken and conceded (both on target and from the box), as well as the percentage of ball possession.

With respect to the indicators selected, Napoli and Atalanta should have achieved more points than the Italian Serie A champions Juventus. However, Massimiliano Allegri’s players were much more efficient. In the Greek top division, both Olympiacos and AEK Athens had a greater pitch production than champions PAOK. Marcelo Bielsa’s Leeds United tops the production rankings in the English Championship.

According to pitch production, Lucien Favre’s Borussia Dortmund should only have ranked fourth in the German Bundesliga behind Bayern Munich, RB Leipzig and Bayer Leverkusen. The Ruhr team was thus particularly efficient. In Turkey, ?stanbul Ba?ak?ehir virtually outranks Be?ikta? and Galatasaray. More data is available in the CIES Football Observatory Performance Atlas powered by InStat data.

Issue number 261 of the Weekly Post presents the top 50 list of the U20 players from the big-5 with the highest transfer value according to the CIES Football Observatory algorithm. The English full international Jadon Sancho heads the table with an estimated value of €150M. Borussia Dortmund’s winger outranks Arsenal’s Mattéo Guendouzi (€70M) and AS Roma’s Nicolò Zaniolo (€67M).

Four other big-5 league players born on or after January 1st 1999 have an estimated value greater than €50M: Kai Havertz (Bayer Leverkusen), Declan Rice (West Ham), Gianluigi Donnarumma (Milan AC) and Vinícius Júnior (Real Madrid). Footballers from 18 national associations feature in the top 50 list. The most represented country is France (13 players), followed by England (9).

The updated transfer valuations for all players from the five major European competitions are available here.
