Issue number 356 of the CIES Football Observatory Weekly Post analyses the data produced by our partners SkillCorner to unveil the average sprinting (>7.0 m/s or 25.2 km/h) distance per team in 27 leagues worldwide. The values stretch from 2.23km at Marcelo Bielsa’s Leeds United to only 1.04km at the Ukrainian side Metalist 1925 Kharkiv.

In only five teams among the 492 surveyed, players sprinted for more than 2 kilometres per match: the Swiss and Champions League side BSC Young Boys, the Dutch clubs SC Cambuur and Heracles Almelo, as well as the English Championship leaders AFC Bournemouth. Athletic Club (1.99km) tops the table in the Spanish Liga, Milan AC (1.91km) in the Italian Serie A, AS Monaco (1.89km) in the French Ligue 1 and Bayern Munich (1.85km) in the German Bundesliga.

The average sprinting distance per league vary from 1.70km in Swiss Super League and 1.26km in Scottish Premiership, with an overall average of 1.51km per team and match. The highest value at big-5 league level was recorded in the Spanish Liga (1.68km), while the lowest was measured in the German Bundesliga (1.47km). Follow us on Twitter, Facebook or Instagram for more exclusive football data analysis.

After the drop in 2020 within the context of the pandemic, the part of players imported from abroad in the squads of teams from 31 European top divisions has started to rise again. This is one of the main findings from the annual census carried out since 2009 by the CIES Football Observatory research team, published in the 69th edition of the Monthly Report.

Expatriate footballers currently represent 41.9% of players in the 473 clubs surveyed. For the first time in history, players having grown up outside of the association of their employer club represent the majority of footballers within the five major European championships, with a maximum of 60.6% in the Italian Serie A and a minimum of 38.1% in the Spanish Liga. The greatest proportion of expatriates overall was recorded in Cyprus (69.9%).

Despite the growth of expatriates, the presence of club-trained players has also continued to increase after the pandemic. However, the percentage footballers having been in their employer club for at least three seasons between 15 and 21 years of age remains much lower than in 2009: 18.0% as opposed to 23.1%. The slight recent increase is chiefly explained by the rise observed in the least competitive leagues, where clubs suffered the most from the pandemic.

The proportion of players recruited during the year decreased for the fourth consecutive time, reflecting a less frenetic transfer market. The percentage of new signings among squad members went down from 44.9% in 2017 to 40.4% in 2021. The longest average stay in the first team squad of the employer club was recorded for CSKA Moscow (4.83 years), followed by Real Madrid, Athletic Club, Borussia Mönchengladbach and Manchester City.

Issue number 355 of the Weekly Post ranks big-5 league clubs according to the CIES Football Observatory’s Sustainable Squad Management (SSM) Index. The latter highlights teams built to last by combining players’ age (the younger, the better), average stay in the first team squad (the longer, the better) and contract duration (the longer, the better). The employment rate of each is also considered as a weighting factor (more minutes, greater importance).

Manchester City, Real Sociedad and Liverpool currently hold the most sustainable squads. Guardiola’s team fields slightly younger line-ups than big-5 league rivals (27.06 years vs 27.13). Moreover, players fielded have been for much longer in the first team squad (3.32 years vs 2.34) and have much longer contracts (3.32 years vs 2.30). The Basques field much younger line-ups (25.62 years) and their values in terms of stability (3.04 years) and contract duration (2.49 years) also are above the average.

Spezia Calcio fielded so far the youngest line-ups (24.61 years), while the longest average stay for players fielded was recorded for Burnley (4.07 years). The longest “on the pitch” average contract remaining duration was measured for Arsenal (3.69 years). The Gunners also field by far the youngest line-ups in the English Premier League (24.86 years). However, their stability is for now well below the big- 5 league average (1.75 years only). More information on the SSM Index is available here.

Issue number 354 of the CIES Football Observatory Weekly Post presents the most active dribblers in 33 leagues worldwide according to the data of our partners InStat. Only players having attempted at least 40 dribbles in the current season (or in 2021 for the Brazilian Serie A) are included in the rankings. A dribble is defined as an active action performed by a player in order to get through an opponent.

Players are ranked according to a Dribble Index, i.e. the percentage of successful dribbles divided by the dribbling attempt frequency (minutes of play per dribble). Then highest score overall was recorded for Wolverhampton Spanish winger Adama Traoré (11.2), ahead of Universidad de Chile’s Argentinean Nahuel Luján (9.7) and CSKA Moskow’s Nigerian Chidera Ejuke (9.3).

At the top of the rankings in the other main major leagues are Erick de Arruda (Cearà SC) in Brazil, Rafael Leão (Milan AC) in Italy, Kamaldeen Sulemana (Stade Rennais) in France, Cody Gakpo (PSV Eindhoven) in the Netherlands, Alphonso Davies (Bayern Munich) in Germany, Jordan Carrillo (Santos Laguna) in Mexico, Ivo Rodrigues (Famalicão FC) in Portugal and Vinícius Júnior (Real Madrid) in Spain.

AFC Ajax tops the CIES Football Observatory 2021 rankings of clubs having trained the most footballers playing in 31 top divisions of UEFA member countries. The Dutch team nurtured 81 players currently active in these championships, six more than Shakhtar Donetsk. Real Madrid and Barcelona co-head the table for players active in the five major European leagues (42). The top 100s are accessible for free here.

The CIES Football Observatory also developed the Training Index, an indicator weighting the number of players trained according to the sporting level of their employer clubs (through a coefficient based on domestic league and international club competitions results), their employment rate (over the last year), as well as their age (the younger, the better). Ajax also tops this table for players in the 31 European top divisions surveyed, ahead of Sporting Clube de Portugal and Real Madrid.

The highest Training Index when only considering big-5 league footballers was recorded for Real Madrid, ahead of FC Barcelona and Paris St-Germain. Ajax, Sporting Clube and Anderlecht are the best-ranked non big-5 league teams. As per UEFA definition, training clubs are those where footballers have played for at least three years between the ages of 15 and 21. The season during which players celebrated their 15th and 21st birthday are also included.

Issue number 352 of the CIES Football Observatory Weekly Post ranks teams from 41 leagues worldwide according to the ratio between big chances created and conceded as per data from our partners InStat. A big chance defines a clear-cut chance to score a goal. Partizan Belgrade (5.0) recorded the best ratio out of the 680 clubs surveyed, ahead of AFC Ajax (4.3) and RB Salzburg (4.1).

Manchester City tops the table for the five major European leagues with a ratio of 3.3. Guardiola’s side creates on average 8.4 big chances per game, while only conceding 2.6 to their opponents. Bayern Munich (3.0) and Paris St-Germain (2.4) complete the podium for the big-5, while Everton is fourth (2.3). At the bottom of the rankings are Granada, Greuther Fürth, Norwich City and Southampton.

River Plate is the most dominant team in the Argentinean top division with a big chance ratio of 2.5, ahead of Club Estudiantes, Vélez Sarsfield and Boca Juniors. In Brazil, Flamengo (1.8) outranks CA Mineiro, Fortaleza EC and Ceará SC. Per league, the number of big chances per game vary between 13.6 in the Swiss Super League down to only 8.4 in the Romanian Liga I.
