Distances covered: SkillCorner data analysis

Since last summer, the CIES Football Observatory has had the pleasure of working with the French leading company SkillCorner, specialised in the generation of physical data on football players. The 68th Monthly Report analyses the distances covered, notably according to running speed, for 7,855 matches played during the 2020 or 2020/21 seasons in 31 leagues from both Europe and America.

The study shows that players from European teams tend to cover more ground than those from South American clubs, which reflects a more rapid playing style. However, the gaps between the competitions analysed are not very marked. The values per outfield player and match stretch from 10.3km for the Spanish Liga and 9.6km in the Brazilian Serie A.

A significant link exists between the players’ age and distances covered, whether for total distance or that ran in high intensity (> 19.8 km/h). The strongest relation was recorded between the forwards’ age and high-speed runs. This finding confirms that the propensity of strikers to cover distances at high intensity decreases over the years, revealing the advantage of having young forwards in the squad.

Important differences at the level of total distances covered and the speed of runs also exist between positions. Midfielders run the most (10.6km per match on average), while centre backs the least (9.2km). Wingers cover the greatest distance both in high intensity (932m) and when sprinting (211m). In these cases too, the lowest figures were measured for centre backs.

Fielding of expatriates: European rankings

Issue number 351 of the CIES Football Observatory Weekly Post ranks clubs in 31 top divisions from UEFA member associations according to the percentage of domestic league minutes played by expatriates. The highest value overall was recorded for the Greek side Aris FC (98.4% of minutes), while Udinese Calcio (88.0%) tops the rankings for big-5 league clubs ahead of Chelsea FC (86.8%).

LOSC Lille, RB Leipzig and Atlético Madrid are the most foreign-oriented clubs in the other three major European championships, while Rangers FC tops the table in Scotland, Boavista FC in Portugal, Fatih Karagümrük in Turkey and SBV Vitesse in the Netherlands. The notion of expatriates refers to footballers who grew up in a different association from that of the employer club.

Only two teams out of the 474 surveyed did not field any expatriate player in domestic league games: the Ukrainian side FK Desna and the Basques of Athletic Club. The CIES Football Observatory is also happy to unveil that an improved version of the Demographic Atlas with current season’s data is now available here. Enjoy the tool!

Big-5 league clubs’ estimated squad transfer values

Issue number 350 of the Weekly Post presents the estimated squad transfer values of the 98 teams in the big-5. The figures were calculated on the basis of the exclusive CIES Football Observatory algorithm. The two teams having invested the most to sign their current players, Manchester City and Manchester United, also are at the top of those with the highest estimated squad value.

The Manchester teams would potentially collect more than €1.2 billion in transfer indemnities if they decided put all their current squad members on the market. Chelsea completes the podium with an estimated squad value of €946 million. Barcelona heads the rankings in the Spanish Liga (€896M), Bayern Munich in the German Bundesliga (€890M), Paris St-Germain in the French Ligue 1 (€808M) and Juventus in the Italian Serie A (€618M).

The estimated transfer value of all English Premier League players totals €8.9 billion (€445M per team on average). For the other leagues of the big-5, these figures are €5.3 billion for the Spanish Liga (€263M per club), €4.5 billion for the German Bundesliga (€251M), €4.4 billion for the Italian Serie A (€222M) and €3.4 billion for the French Ligue 1 (€172M). The individual estimates for all big-5 league players are available here.

Youngest teams: Monaco and Leverkusen at the top

Issue number 349 of the CIES Football Observatory Weekly Post ranks teams from 72 top divisions worldwide according to the average age of line-ups fielded in the current season and the percentage of minutes played by footballers who did not yet celebrate their 21st birthday. Monaco played so far with the youngest line-ups in the five major European leagues (24.3 years), while Bayer Leverkusen fielded U21 players for the highest percentage of minutes (24%).

With 23% of domestic league minutes played by U21 footballers, Barcelona ranks second in the big-5 ahead of four French Ligue 1 teams (Nice, Rennes, Marseille and Reims). Arsenal fielded so far the youngest line-ups in the English Premier League (25.0 years), while Spezia did so in the Italian Serie A (24.8 years) and Real Sociedad in the Spanish Liga (25.5 years). At the opposite end for each big-5 league are Lazio (30.3), Elche (29.9), Burnley (29.3), Bochum (28.7) and Clermont Foot (28.0).

The Latvian side FK Metta fielded the youngest line-ups overall (20.2 years on average) and the Armenians of BKMA Yerevan top the table for the highest percentage of domestic league minutes played by U21 footballers (79%). On the contrary, 89 of the 1’041 teams surveyed did not field any U21 player, among which Wolfsburg, Newcastle United, Atlético Madrid, Juventus, West Ham United, Rangers FC, Trabzonspor, Mamelodi Sundowns, Columbus Crew and Al Hilal SFC.

Big-5 league rankings: the forecasts

The 348th edition of the CIES Football Observatory Weekly Post presents the forecasts for the 2021/22 season at the level of the five major European leagues. The statistical model used for this purpose includes the players’ experience, transfer fee investments to assemble squads, as well as each team’s performance in the last 365 days.

With respect to 2020/21, the only change from a champions perspective is supposed to take place in Spain, with Real Madrid finishing ahead of Atlético and Barcelona. In England, the top four would be the same as last season, with Tottenham fifth ahead of Everton. Norwich City, Watford and Newcastle United are the main candidates for relegation.

In Italy, Inter Milan would outrank Napoli and city rivals Milan AC, with Juventus only sixth. Wolfsburg are the most likely runners-up in the German Bundesliga, ahead of Borussia Dortmund and Bayer Leverkusen. In France, after Paris St-Germain, we would find the two Olympique (Marseille and Lyon in this order), while St-Etienne is a serious candidate for relegation.

Ball masters worldwide: PSG shows the way

Issue number 347 of the CIES Football Observatory Weekly Post ranks teams from 36 domestic leagues worldwide – 32 in Europe and 4 in the Americas – according to the number of passes made per match during current season as per data provided by our partners InStat. Paris St-Germain tops the rankings with an average of 738 passes.

In terms of the percentage of passes made in the opposite half, the Ukrainians of Shakhtar Donetsk are clearly at the top with an astonishing 68%, ahead of Manchester City (60%) and Ajax (57%). At the bottom of the rankings are Cosenza (22%) and two big-5 league teams: Norwich City and Elche (both 25%). As for the rate of accurate passes, the values vary between 92.6% for Paris St-Germain and Lazio, down to just 66.1% for Salernitana.

Regarding the four non-European leagues included in the sample, the highest figure for passes was measured for Flamengo (606, 87.7% of which accurate), while the lowest was observed for the Mexican side Atlético San Luis (336, 76.8%). Flamengo tops the table also for the proportion of passes in the opposite half alongside the Colombians of Deportes Quindío (50.3%). Another Brazilian team, Grêmio, complete the podium.
