The top ranked teams in the remaining big-5 leagues are Olympique Lyonnais (6.7 shots per goal, 5th place), Eintracht Frankfurt (6.9, 7th), Chelsea (7.0, 10th) and Palermo (7.5, 12th).

Conversely, at the bottom end of the table are Hambourg (22.9), Aston Villa (20.9), Torino (17.1), Granada (16.9) and LOSC Lille (15.2). These figures both reflect a lack of efficiency and the difficulty in taking up a favourable position to shoot. As a matter of example, Aston Villa scored only two goals out of 109 attempts in second halves!

All these statistics were calculated from data provided by our partners Opta Pro. They are to be found here.

Juventus also led for a majority of domestic league minutes (52.0%). This figure was below 40% for Paris St-Germain (39.8%), Barcelona (39.6%) and Manchester City 38.8%). The record low at big-5 league level was recorded for Sunderland (10.3%). This does not augur well for the Black Cats.

The figures for the 98 big-5 league clubs are to be found here.

The report indicates that stability gives clubs a competitive advantage over rival teams, be it on a sporting level (better medium and long-term results) or an economic one (a greater capacity to launch careers of club-trained players and generating revenues through their transfer).

Stability indicators such as the average length of stay of players in their club or the percentage of new signings in the squad thus show their true worth when judging the pertinence of management strategies instigated by club managers.

Well-informed fans of the most unstable teams have good reason to be anxious. In order to protect football from the bad practices of certain managers, to promote training and to increase team competitiveness, it would thus be timely to consider the introduction of a limitation on the number of transfers allowed.

True to its reputation, our research group is at the disposal of football stakeholders to analyse such a scenario. This would notably be about defining more precisely the boundaries of such a limitation on transfers in order to attain the desired goals, without interfering with the free movement of players or provoking a distortion of the market with regard to the upholding of the principle of proportionality.

Issue number 94 of the Big-5 Weekly Post also deals with the subject of club stability by presenting the date of arrival of current squad members for clubs ranked in first and last position in the table of their respective league. This analysis also allows us to highlight the importance of squad stability for sustainable success.

With the exception of Raheem Sterling, in the top 10 positions of the ranking are only players under contract with teams that are still competing in the Champions League:

• Lionel Messi (Barcelona) : 220 million €
• Cristiano Ronaldo (Real Madrid) : 133 million €
• Eden Hazard (Chelsea) : 99 million €
• Diego Costa (Chelsea) : 84 million €
• Paul Pogba (Juventus) : 72 million €
• Sergio Agüero (Manchester City) : 65 million €
• Raheem Sterling (Liverpool) : 63 million €
• Francesc Fàbregas (Chelsea) : 62 million €
• Alexis Sánchez (Arsenal) : 61 million €
• Gareth Bale (Real Madrid) : 60 million €

The club with the most representatives in the top 100 of the table is Spanish giant and Champions League title holder Real Madrid:

• Cristiano Ronaldo: 2nd, 133 million €
• Gareth Bale: 10th, 60 million €
• James Rodríguez: 15th, 50 million €
• Isco Alarcón: 17th, 45 million €
• Karim Benzema: 21st, 43 million €
• Toni Kroos: 23rd, 41 million €
• Luka Modri?: 27th, 37 million €
• Sergio Ramos: 40th, 33 million €
• Daniel Carvajal: 68th, 25 million €
• Raphaël Varane: 87th, 23 million €
• Marcelo Vieira: 94th, 22 million €

The transfer values are calculated using an exclusive algorithm developed on the basis of over 1,500 fee paying transfers occurred since 2009. The variables included in our exclusive econometric model refer to player performances (matches, goals, dribbles, etc.), their characteristics (age, position, contract duration, etc.), as well as competition level and results achieved by their teams (clubs and national sides).

For more information, you are kindly invited to read chapter four of this paper on the CIES Football Observatory’s approach for sustainable success.

This tool is freely available online from our website. It enables anyone to analyse the state of the game in 31 European countries and to follow its progress from year to year. The indicators offered study the characteristics of players from over 500 first division clubs from the perspective of age, height, mobility, training, origin, etc.

By consulting the Atlas, you can notably learn that there is almost 10cm of difference between the club with the tallest players, Diósgyör (186.3cm on average), and that with the shortest ones, Barcelona (177.3).

The Atlas also allows for comparisons between leagues. Regarding age, for example, it shows that the Italian Serie A regroups the oldest footballers (27.3 years on average), while the Dutch Erdivisie is made up of the youngest ones (24.2).

Issue number 92 of the Big-5 Weekly Post helps situate the five major championships in the European context from the point of view of the average age of squad members. It also presents the average age for the 98 big-5 league clubs. The Post notably shows that more than 5 years separate the youngest club, Valencia, from that which gathers the oldest players, Atalanta.

From January onwards, the Football observatory’s academic team will also offer monthly reports instead of our annual paying publications. Like our Digital Atlas, these will also be freely accessible from our website. The first issue will cover the topic of club instability. Moreover, we shall continue the publication of the Big-5 Weekly Post. We are open to sponsorship proposals.

In autumn 2015, we also plan to publish a book destined for the general reader summarising the key points garnered from our analyses over the past decade. There are indeed over 20,000 football enthusiasts like yourselves now on our mailing list. We warmly thank your for your interest in all our numerous areas of initiative.

Happy Christmas and best wishes for 2015!

Moreover, issue number 91 of the Big-5 Weekly Post presents the results of the analysis of the ASAR ratio for clubs from the five major European championships. The ratio is obtained by dividing the average stay of players in the first team squad of their employer club (the longest, the best) with their age at recruitment (the youngest, the best).

Indeed, the analyses carried out since 2005 show a strong correlation in all countries between this ratio and the results obtained by clubs at the end of the season. It is thus not surprising to note that the five clubs that are currently at the top of the table in their respective league are also in the top 20 positions of the ASAR ranking at European level:

• Real Madrid (2nd both at big-5 league level and Spain)
• Juventus (7th and 1st in Italy)
• Bayern Munich (9th and 2nd in Germany)
• Chelsea (11th and 1st in England)
• Marseille (19th and 2nd in France)

From an ASAR perspective, the most over-performing teams so far are Sevilla, Genoa and Valencia. Conversely, Real Sociedad, Borussia Dortmund, Everton, Cagliari and Lille clearly under-performed.

Our academic team is at the service of professional clubs to study their squads in greater detail.

Thanks to our tool, anyone can obtain an accurate, up to date transfer value for players taking part in the five principle markets of European football: the English Premier League, Spanish Primera Liga, German Bundesliga, Italian Serie A and the French Ligue 1.

Our statistical model is based on almost 1,500 fee paying transfers having taken place at big-5 league club level from 2009 onwards. The correlation between estimated and actually paid sums is greater than 80%. This shows that we have been able to reveal the logics of the transfer market. This allows us to anticipate events and highlight market bias.

Our team is at service of market actors for expert audits for both big-5 league players and professional footballers playing in other championships at worldwide level.
Do not hesitate to access the calculator here.

Our rankings highlight not only the best performing players overall, but also those who performed the best with regard to teammates. This approach allows us to pick out more players who are not yet part of the top clubs. This is particularly useful from a scouting perspective. To limit bias, only footballers having played at least 66% of match time since the start of the season are included in the study.

In absolute terms, the best big-5 league players at present are Cristiano Ronaldo (Real Madrid) both in shooting and chance creation, Eden Hazard (Chelsea) in take on, Xabi Alonso (Bayern Munich) in distribution, Mathieu Coutadeur (Lorient) in recovery and Javi Manquillo (Liverpool) in rigour.

At the top of the relative rankings, we find Charlie Austin (QPR) in shooting, Xabi Prieto (Real Sociedad) in chance creation, Federico Cartabia (Córdoba) in take on, Roberto Trashorras (Rayo Vallecano) in distribution, Alaixys Romao (Marseille) in recovery and Mathieu Bodmer (Nice) in rigour.

Actors from professional clubs can contact us to enquire about our range of products in the domain of performance analysis.

Key performance indicators

• Shooting: ability to exploit goal opportunities through accurate shooting
• Chance creation: ability to putting teammates in a favourable position to score
• Take on: ability to create advantageous situations by successfully challenging opponents
• Distribution: ability to keep a hold on the game through efficient passing
• Recovery: ability to minimise opponents’ chances through proficient interception work
• Rigour: ability to minimise opponents’ chances through robust duelling

In the other championships, the most “expensive” matches this season were Manchester City-Chelsea (578 million €), Paris St-Germain-Marseille (503 million €), Bayern Munich-Borussia Dortmund (272 million €) and Inter-Napoli (263 million €).

This analysis shows the increasing impact of money at the highest level of European football and the difficulty encountered by the vast majority of teams to reach the performance levels of the richest clubs. This state of affairs leads to more predictable results.

Thus, the five clubs touted by our research team as favourites at the start of the season are either in the first (Bayern Munich, Chelsea) or second place (Paris St-Germain, Barcelone, Rome) of their respective championships.

The expatriate presence is particularly high in the English Premier League (59.3%. A new record high since 2009 was measured this season in Italy (54.8%) and Spain (38.9%). Expatriates represent 43.5% in Germany and 31.6% in French Ligue 1. Compared to one year ago, the percentage of football migrants went up in all big-5 leagues with the exception of the English Premier League (-1.6%).

The biggest increase since 2009 was registered in Italy: from 42.4% to 54.8% (+12.4%), while the strongest growth since November 1st 2013 was measured in the German Bundesliga: from 38.1 to 43.5% (+5.4%).

For the first time in history, the main exporting country is France: 113 players compared to 112 for Brazil (former leader) and Argentina. The strongest increase since 2009 was recorded for Spain (from 17 to 58 players in foreign big-5 leagues). During last year, the biggest growth was for Serbia (28 to 39, +11) and Belgium (31 to 41, +10).

Since the start of the 2014/15 seasons, the teams having fielded the shortest line-ups per league are Barcelona (176.4 cm), Nice (177.0 cm), Empoli (178.2 cm), Hertha (179.4 cm) and Manchester City (179.8 cm).

Conversely, at the head of the rankings of the tallest formations during current season are Stoke City (188.0 cm), Schalke 04 (186.7 cm), Verona (186.2 cm), Monaco (185.5 cm) and Elche (183.6 cm).

Key topics of the Forum also include: creating a global standard for live sport data, low cost performance tools, coach-led analytics, data in science and sport medicine, evidence-based decision making in modern coaching, monetising sports data and video content across multiple platforms, interactive panel discussions, as well as networking activities.

Out of the 43 big-5 league footballers trained at Barcelona, 13 are still playing for the Catalan club. Only Olympique Lyonnais, Athletic Bilbao and Real Sociedad have a greater number of club-trained players in their current squad. To be able to rely on homegrown talent in this way has provided a key competitive advantage for Barcelona over the last decade. Munir El Haddadi and Sandro Ramírez are the latest examples of this strategy.

Barcelona is also at the top of the table of clubs having trained the most footballers playing for other big-5 league teams (30), ahead of Real Madrid (26) and Manchester United (24). This finding not only highlights the quality of training provided by these top teams, but also demonstrates the difficulty for youth academy players to breakthrough into the first team squad of the most competitive club. This is unlikely to change in the near future, irrespective of the legal framework in force.

River Plate heads the ranking for clubs not participating in the big-5 leagues. The Argentinean team has trained 17 players currently employed by teams in the five major European championships, which is two more than Le Havre, Ajax and Munich 1860.

Issue 86 of the CIES Football Observatory Big-5 Weekly Post also shows that the percentage of club-trained players went down for the fourth consecutive season and has now reached a new record low: 17.2% of squad members. This percentage varies between 24.6% in France and 9.6% in Italy. To be considered club-trained, a player must have played for at least three seasons between the ages of 15 and 21 for his employer club (UEFA criterion).

At the opposite end of the table, Manchester City fielded the third oldest line-up at big-5 league level: 29.3 years (highest figure in the English Premier League). This suggests that fresh blood is needed to maintain top level performance standards over the long term. Only Verona (31.0) and Torino (30.3) fielded more seasoned players than Manchester City.

Since 2008/09, the youngest line-up in the big-5 was fielded by Nice: 22.1 years on average against Evian on 10.05.2014. Conversely, the team having fielded the oldest line-up is Milan AC: 33.3 years against Catania on 03.05.2009.

The data on the last match day for all big-5 league clubs is available in the 85th Weekly Post. For more information, please contact us at football.observatory@cies.ch

Since the beginning of the English Premier League season, Manchester United achieved the third highest score in points achieved by minute played, ahead of Manchester City (5th). This suggests that Louis van Gaal’s team should be able to further improve its results in the near future. The gap measured with respect to Chelsea is indeed not as significant as at the end of the matches played so far (-0.42 compared to -1.14). Conversely, Arsenal is ranked only 16th.

At individual player level, in the English Premier League Marcos Rojo (Manchester United) has achieved the most points by minute played: 2.39 on average. The lowest figure among footballers who have played at least half of total match minutes was recorder for Niko Kranj?ar (QPR, 0.31).

Players with the most impressive statistics in the remaining big-5 European leagues are Pablo Piatti (Valencia), Dimitri Payet (Marseille), Arjen Robben (Bayern) and Angelo Ogbonna (Juventus). In contrast, the least successful players so far this season besides Niko Kranj?ar are Xabi Prieto (Real Sociedad), Mathieu Peybernes (Bastia), Julian Draxler (Schalke 04) and Daniele Conti (Cagliari).

The minute by minute rankings will be updated after each championship round. They will be available throughout the season on the CIES Football Observatory website.

The best performing players in the other positions are Giorgio Chiellini (centre back), Jordi Alba (full back), Xabi Alonso (central/defensive midfielder) and André-Pierre Gignac (forward). Only footballers who played at least 60% of championship minutes are included in the analysis.

Many footballers who did not yet represent a national A-team are to be found in the top 15 positions of the rankings: Robin Knoche (Wolfsburg), José Fonte (Southampton), Antonio Balzano (Cagliari), Layvin Kurzawa (Monaco), Juan Bernat (Bayern Munich), Roberto Pereyra (Juventus), James Ward-Prowse (Southampton), Manuel Nolito (Celta Vigo) and Wissam Ben Yedder (Toulouse). All these footballers deserve a chance to play for their country of origin.

Players are ranked according to their production and efficiency in six areas of the game (see below). The six key performance skills taken into account are weighted differently per position according to their impact on club results. Consequently, for example, rigour is more important for centre backs than for forwards. For more comparability, the rankings also consider the differences in the intensity and style of play between leagues.

CIES Football Observatory key performance skills

• Shooting: ability to take advantage of goal opportunities through accurate shooting
• Chance creation: ability to put teammates in good position to score
• Take on: ability to create dangerous situations by successfully challenging opponents
• Distribution: ability to hold the grip on the game through efficient passing
• Recovery: ability to minimise goal opportunities for opponents through proficient ball recovery
• Rigour: ability to minimise goal opportunities for opponents by efficiently blocking their actions

A new record high was also measured with regard to the percentage of transfer fees invested with 49% of the ten most active clubs now involved in this activity. In addition, the level of transfer fee compensation paid by clubs in the most active league – the English Premier League - reached a new peak of 45% of total transfer expenditure.

All of these findings show the increasing concentration of fee paying transfer activity at the very top of the football pyramid. At the same time, and as shown in issue 81 of the Big-5 Weekly Post, an increasing proportion of fees invested do also benefit other big-5 league clubs (72% during the last transfer window compared to 67% for the five previous years). These figures highlight the ongoing transformation of the transfer market into a zero-sum game involving a closed circle of top level teams and with significant amounts of money made by dominant intermediaries and/or third-parties.

The club that invested the most on the transfer market since 2008 was Real Madrid €750 million, closely followed by Manchester City (€733 million).

Data refers to the indicators of average age, average height, % of club-trained players, % of internationals, % of expatriates and average stay.

More detailed data relating to club level analysis is presented in our annual publications: Annual Review (big-5 leagues) and Demographic Study (31 top division leagues in Europe).

We also kindly remind you that an online tool to assess the transfer value of big-5 league players is available here.
