The 41st CIES Football Observatory Monthly Report analyses the link between ball possession and results in 35 European leagues. While this link is undeniable, it is only from a certain level that ball control allows teams to improve significantly their results. This is probably the source of the erroneous but widespread idea that possession is not a key factor for success.

The 70 champions of the last two seasons in the 35 leagues analysed had an average possession of 57% during their winning season. Only 10% of champions won their league with a ball possession of less than 50%: Spartak Trnava, RC Strasbourg, Stade de Reims, AIK Solna, FC Midtjylland, Spal 2013 and CFR Cluj. None of the 70 champions completed fewer passes in the attacking third of the pitch than their opponents during the title winning season.

The analysis at match level for all the possession indicators taken into account shows that a team can sometimes accept an opponent’s domination, especially when they are winning. However, this is not a successful strategy in the longer term as it implies too many risks of conceding the first goal without being then able to put sufficient pressure on opponents. The data used were generated by the specialist sports company InStat. More information is available on demand.

Issue number 246 of the CIES Football Observatory Weekly Post analyses the pitch production of big-5 league clubs during the first part of the current season to highlight if they have over- or under-performed in terms of points achieved. The findings suggest that Manchester City will finally beat Liverpool in the English Premier League title race.

Manchester City achieved so far 5% of points per match less than expected according to its pitch production. Conversely, Liverpool obtained 15% more and its results are supposed to decline in the second part of the season. The over- or under-performance were calculated according to a regression model built on the 2016/17 and 2017/18 seasons including shots on target, ball possession and shots conceded from the box. The data comes from the specialist company InStat.

In the other big-5 leagues, the pitch production of three out of four teams at the top of the table should allow them to lift the trophy: Barcelona in Spain, Juventus in Italy and Paris St-Germain in France. However, in Germany, the analysis suggests that Bayern Munich will finally outrank the current leader Borussia Dortmund. The data for 27 further European competitions are available on demand. More data is also accessible in the exclusive CIES Football Observatory Performance Atlas.

The first Weekly Post of the year presents the 100 big-5 league players with the highest transfer value according to the exclusive CIES Football Observatory algorithm. The 20-year-old French prodigy Kylian Mbappé (€218.5 million) tops the list ahead of Harry Kane (€200.3m) and Neymar (€197.1m).

Among the 27 footballers with an estimated value of more than €100m, sixteen play in the Premier League, five in the Liga, three in the Serie A, two in the Ligue 1 and one in the Bundesliga. Eleven nations have representatives with an estimated value of more than €100m: Brazil (6 players), England (5), France (5), Argentina (2), Portugal (2), Belgium (2), Egypt (1), Germany (1), Senegal (1), Uruguay (1) and Italy (1).

The transfer values for all big-5 league players are available online. A research note explaining the methodology used by the CIES Football Observatory and the criteria included in the algorithm is accessible here. Please contact us for more information and consultancies.

The last CIES Football Observatory Weekly Post of the year 2018 highlights players whose teams have achieved the most or least points per match when they were in the starting 11 than when this was not the case. The most positive gap in absolute was recorded for Christophe Jallet (OGC Nice): 7 wins out of the 7 matches that he started compared to only 0.44 points per match for the remaining games.

In the other big-5 leagues, the most positive gaps for players who have been present or absent at least five times in the starting 11 were recorded for Diogo Jota (Wolverhampton), Rubén Rochina (Levante), Andreas Beck (Stuttgart) and Goran Pandev (Genoa). Pedro Rodríguez and Ross Barkley were so far also lucky carriers for Chelsea: 100% of points for matches started in both cases.

Conversely, the most negative gaps per championship were registered for Massimo Gobbi (Parma), Gerard Gumbau (Leganés), Denis Zakaria (Borussia Mönchengladbach), Anthony Knockaert (Brighton & Hove) and Olivier Boscagli (OGC Nice). However, it is useful to remind that these results are in part a random fact.

The CIES Football Observatory is pleased to announce the launch of a parallel research group within the Centre International d’Étude du Sport (CIES). Led by Fernando Roitman, this new team focuses on aspects of sports governance, finance, legal and development.

The freshly published ‘Governance Structures at National Association Level’ report focuses on a selection of 20 countries from all six confederations and provides insight into one of the crucial aspects of world football. The study analyses five main areas: General Assembly (GA), Executive Committee (ExCo), President, judicial bodies and reporting activities. As findings are standardised in their form, the document allows benchmarking between individual case studies and the identification of potential trends across different regions of the world.

Issue number 243 of the CIES Football Observatory Weekly Post presents the top 20 tables for big-5 league players whose transfer values have increased the most during the last three months both in absolute and relative terms. At the head of the two rankings is the fresh English full international and Borussia Dortmund player Jadon Sancho: +€78 million and +806%.

Apart from Sancho, four players have seen their transfer value increase by more than €30M: João Cancelo (Juventus), Andrew Robertson (Liverpool), Richarlison (Everton) and Thilo Kehrer (Paris St-Germain). Many hot prospects are in the top 20 list of players whose value has risen the most in relative terms. The highest figures per league were recorded for Jadon Sancho in Germany, Moise Kean in Italy, Stanley N’Soki in France, Isaac Success in England and Júnior Firpo in Spain.

This analysis was performed using the exclusive CIES Football Observatory algorithm. A detailed explanation of the approach developed is available in this research note. The transfer value of all big-5 league players is freely accessible on the CIES Football Observatory website. The figures published refer to the estimated price for the most likely recruiting club. Moreover, a calculator was developed to allow users assessing the transfer value of players worldwide. However, this tool only provides rough estimates. Deeper analysis is available on demand.

The 40th Monthly Report of the CIES Football Observatory analyses the evolution of competitive balance in 24 European leagues over the last 10 seasons. The study reveals a clear trend towards a greater imbalance. The level of imbalance is particularly marked and on the increase in the big-5 leagues and the Champions League, where the economic divides between teams are very strong.

In 2017/18, big-5 league champions achieved a record of 83.3% of points. This proportion is 10% greater than that measured in 2008/09. Over the ten seasons studied, the biggest average goal difference per match was measured for the UEFA Champions League: 1.58 goals. The premier competition of European football is also that presenting the highest proportion of matches with a goal gap of at least three: 21.0%.

According to the Report, “the concentration of resources goes hand in hand with the concentration of talents. Many teams and leagues are confined to a stepping-stone role for up and coming players. This permits the generation of profits on the transfer market. However, the financial compensations from these transactions are not sufficient to halt the increasing competitive imbalance. The present situation favours the wealthiest clubs. Each day, they increase their sporting, economic and political domination”.

Issue number 242 of the CIES Football Observatory Weekly Post relies on InStat data to present the average effective time of games in 37 European competitions. The Swedish Allsvenskan is the league with the most fluid matches (60.4% of effective time), just ahead the UEFA Champions League (60.2%). The Portuguese Primeira Liga finds itself in the opposite position (50.9%).

The highest effective playing time among the five major European leagues was recorded for the German Bundesliga (58.5%), while the lowest was measured for the Spanish Liga (55.8%). As for the Champions League, Europa League games are more fluid than the average observed at the level of the 35 competitions surveyed: 57.1% of effective time compared to 55.3%.

The highest percentage of minutes in which the ball was in play for clubs in national competitions was recorded for matches of the Swedish side GIF Sundsvall (63.7%). This is 18% more than for games of the Portuguese team Feirense. Club Brugge tops the Champions League table (66.2%), while Borussia Mönchengladbach (62.5%), Liverpool (62.2%), Milan AC (61.2%), Barcelona (60.3%) and Paris St-Germain (60.1%) present the greatest figures for the big-5 leagues.

Issue number 241 of the CIES Football Observatory Weekly Post ranks countries according to the number of domestic league minutes played by their representatives in the big-5. The French (=players who grew up in France) top the rankings (19.7% of total minutes) ahead of the Spaniards (15.2%) and the Germans (9.8%). Overall, players originating from 85 countries have taken part in big-5 league matches so far this season.

In each league surveyed, the highest percentage of minutes per origin was measured for nationals. Nevertheless, the gaps are quite marked: from 62.7% in the French League 1 to only 35.3% in the English Premier League. The figures in the remaining championships are 39.0% in the Italian Serie A, 48.5% in the German Bundesliga and 61.0% in the Spanish Liga.

The greatest values for players originating from abroad were recorded for the French in England (10.9%) and Germany (8.0%), the Brazilians in Italy (7.0%) and France (6.8%), as well as for the Argentineans in Spain (also 6.8%). The English Premier League hosts the representatives from the most countries (54). This figure is 50 in the Serie A, 46 in the Ligue 1, 45 in the Bundesliga and only 40 in the Liga.

A brand new Performance Atlas was launched today on the CIES Football Observatory’s website. Powered with data from the leading company InStat, this unique tool presents exclusive pitch statistics at team level for 35 national competitions across Europe: 30 top division and 5 second division ones. The indicators cover all of the three key areas of the game: defence, passing and attack.

At defensive level, Dinamo Zagreb conceded the least shots on target per domestic league game so far this season (1.6). No club surveyed conceded as few passes in the own third of the pitch as Shakhtar Donetsk (40.8). From an attacking standpoint, the highest figures for shots on target and passes in the opponent third per match were recorded for AFC Ajax (9.1) and Manchester City (206).

At passing level, Chelsea FC tops the table for the percentage of accurate passes (89.9%), while Shakhtar Donetsk ranks first with regard to ball possession (67.0%). The tool also presents the data for the least performing teams. To know more about both the CIES Football Observatory and InStat, please contact us.

Issue number 240 of the CIES Football Observatory Weekly Post presents the ten most fielded U21 players in the big-5 leagues and Portuguese top division. Until last Friday, eleven U21 footballers had played the totality of domestic league minutes. Among them notably are hot prospects such as Rúben Neves, Jules Koundé, Arne Maier, Nikola Milenkovi? and Rúben Dias.

Up to six goalkeepers are to be found in the top 10 rankings: Emil Audero (Sampdoria), Gianluigi Donnarumma (Milan), Paul Bernardoni (Nîmes Olympique), Florian Müller (Mainz), Alban Lafont (Fiorentina) and Unai Simón (Athletic Club). With four representatives, FSV Mainz is the most represented club overall: Aarón Martín, Jean-Philippe Mateta, Florian Müller and Ridle Baku.

Overall, footballers born on or after 1st of January 1997 have played 15.4% of total domestic league minutes in the French Ligue 1, 14.7% in the German Bundesliga, 9.8% in the Italian Serie A, 6.1% in the Spanish Liga, 5.3% in the English Premier League and a mere 5.0% in the Portuguese Primeira Liga. The average age on the pitch per league and club is available in the CIES Football Observatory Demographic Atlas.

The long-term work carried out within the CIES Football Observatory focuses, in particular, on the demographic analysis of the football players’ labour market. The surveys carried out over the past decade allow us to reveal very clear trends. As illustrated in Monthly Report number 39, the footballers’ labour market in Europe is becoming deterritorialised by a decreasing presence of club-trained players, a stronger presence of expatriate footballers and greater mobility.

The percentage of club-trained players in the 31 European divisions surveyed reached a new record low on the 1st of October 2018: 16.9% (-6.3% in ten years). The decrease observed during the last year has been the greatest ever recorded (-1.6%). In parallel, the proportion of expatriates has increased to a record level of 41.5% (+6.8% in ten years). The process of internationalisation of squads has accelerated: from an annual growth of 0.55% between 2009 and 2013 to an average increase of 1.17% between 2014 and 2018.

In the conclusion, the authors state that “more and more teams are geared towards the short-term. In an increasingly segmented and speculative context, club officials tend to optimise financial returns on the transfer market to the detriment of more eminently sporting considerations. The increasing instability that results limits the sporting competitiveness of an ever greater number of teams, to the advantage of the wealthiest and better structured clubs, who increasingly dominate the proceedings”.
