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).

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.

Thank you very much for your interest!

The team who was able to generate the most incomes by transferring players to big-5 league clubs is Southampton (120.7 million €). The English team outranks Real Madrid (112 million €) and Chelsea (102.4 million €). The only non big-5 league clubs in the top 10 of the ranking is Porto (83.8 million €). However, a big part of transfer incomes of the Portuguese team was finally due to third-parties that held shares on the economic rights of players transferred.

Among the 46 teams that earned at least 15 million €, only six are not part of big-5 leagues: Benfica, Ajax, Sporting Lisbon, Feyenoord, Dinamo Kiev and Salzburg. More information is available in the 81st issue of the Big-5 Weekly Post.

This year’s predictions take into account the following areas: players’ status, squad cohesion and club ambition. The indicator of players’ status considers minutes played by squad members during the previous season, as well as overall results achieved by their employer club. Squad cohesion refers to the percentage of domestic league minutes played in 2013/14 by footballers who are still at the club, as well as the average number of seasons played by current squad members at the employer team. Finally, club ambition includes the average length of contract duration of first team players, as well as the ratio between the status of new signings and that of footballers released by the club during the last transfer window.

Analysis of the above criteria by the CIES Football Observatory academic team indicates that Chelsea, Barcelona, Paris St-Germain, Bayern Munich and Rome are in the most favourable position to win the title in their respective leagues. Our data also suggests that the runners-up will be Manchester City, Real Madrid, LOSC Lille, Borussia Dortmund and Juventus. Among promoted teams, Leicester City, Burnley, Deportivo La Coruña, Metz and Cologne are well placed to achieve good results. In contrast to this, the following clubs are forecast to struggle in achieving satisfactory results: Crystal Palace, Sunderland, Almería, Nice, Eintracht Frankfurt and Chievo Verona.

Enjoy the season and may the best teams win!

Our ‘right price’ has been calculated as the average between a player’s transfer value both before and after the deal. Significantly, the latter figure also considers the new contract duration of the footballer recruited. Both values have been calculated according to the exclusive CIES Football Observatory statistical model which incorporates nearly 1,500 fee paying transfers completed since 2009 (see below).

Our new data analysis has revealed that overall clubs paid on average 16% more than they invested in the five previous years for players with similar characteristics (add-ons included). This confirms the ongoing inflation trend of the transfer market at the top end of the football pyramid. The inflation trend is mainly due to the sums spent by a handful of wealthy clubs. This was notably the case for Manchester United with regard to Angel Di María (+30 million € between the right price and fee reported), for Paris St-Germain for David Luiz signing (+ 29 million €) and for Real Madrid in the case of James Rodríguez (+25 million €).

At the opposite end of the table, our analysis shows that the existence of buy-out clauses and/or non-sporting related issues allowed Barcelona to reduce their offer for Luis Suárez (-12 million € between the right price and money invested). The same holds true for Chelsea with Diego Costa’s signing (-10 million €). In absolute terms, Mario Balotelli was the most under-paid player (-16 million €).

The full picture for all players transferred for a fee of at least 10 million € (including add-ons) is presented in the 79th edition of the Big-5 Weekly Post. We also kindly remind you that our unique and simple online calculator to estimate the current transfer value of big-5 league players is freely accessible here.

CIES Football Observatory’s statistical model

The CIES Football Observatory academic team has developed an exclusive statistical model to assess the transfer value of players and predict transfer fees. This powerful econometrical model is based on the in-depth analysis of a sample of nearly 1,500 players transferred for a fee from big-5 league teams since the summer transfer window preceding the 2009/10 season. The statistical model developed includes a multitude of variables relating to the following areas: age, length of remaining contract, position, player performance at club level for the most recent and previous seasons, results of the clubs for which players are employed, as well as players’ international experience and results of national team represented.
