The average transfer value of Manchester City’s first team squad members estimated by means of the exclusive CIES Football Observatory algorithm reached a record high of €62.9 million. This is the greatest value measured at big-5 league level ahead of Barcelona (€55.3m) and Tottenham (€51.3m). The figures for all big-5 league teams are available in issue number 226 of the Weekly Post.

English Premier League economic power, outstanding performance, long-term contract duration and youthfulness are the key criteria explaining Manchester City’s first position. Seven of their players have an estimated transfer value of more than €100 million: Kevin de Bruyne, Leroy Sané, Raheem Sterling, Gabriel Jesus, Ederson Moraes, Bernardo Silva and Sergio Agüero.

Among the 31 teams whose players have an average estimated transfer value greater than €10 million are nine clubs from the Premier League, eight from the Serie A, six from the Liga and four from both the Bundesliga and the Ligue 1. The lowest ranked Premier League team, West Bromwich Albion, is 55th out of 98. This also reflects the economic dominance of the English top division.

Issue number 225 of the CIES Football Observatory Weekly Post reveals the most likely World Cup winners according to an exclusive power index. This index combines the average percentage of matches played at domestic league level since July 2017 by the 23 most fielded players per team in the qualifying campaign with the average sporting level of employer clubs. Spain tops the list ahead of Brazil.

During current season, the 23 Spanish footballers most fielded in the qualification stage have on average played 81.1% of domestic league matches. This is the highest figure measured among all participating teams. The average sporting level of the clubs employing Spanish players is also the greatest overall: 1.37. According to these criteria, Spain is well placed to repeat its 2010 success. Three other teams have a power index of more than 80: Brazil, France and Germany.

At the opposite end of the table, the lowest power index was recorded for Panama. Two other nations have a score inferior to 25: Iran and Saudi Arabia. For all these countries, reaching the last 16 stage would be a great achievement. For more information about the features of players employed during the qualifications, please refer to the 30th edition of the CIES Football Observatory Monthly Report.

Issue number 224 of the CIES Football Observatory Weekly Post presents the best performing big-5 league players whose contract runs out at the end of the season. Pepe Reina ranks first ahead of two other goalkeepers (Vicente Guaita and Gianluigi Buffon), as well as Arjen Robben. Only footballers having played at least 1,000 domestic league minutes during the current season are included in the rankings.

For outfield players, the CIES Football Observatory performance index takes into account the production and efficiency in six different areas of the game: rigour, recovery, distribution, take on, chance creation and shooting. For goalkeepers, it includes the minutes per goal conceded, as well as the number and percentage of saves. Results achieved for matches played are also considered as a weighting factor.

In the top 50 list are many relatively young full international players such as Emre Can (Liverpool), Jack Wilshere (Arsenal), Leon Goretzka and Max Meyer (Schalke 04), Sanjin Prci? (Stade Rennais) and Stefan de Vrij (Lazio). As for Goretzka, who already signed for Bayern Munich, all these players will most probably be able to negotiate lucrative contracts in prestigious teams.

Gianluigi Buffon heads the table for the big-5 league players who have been for the longest period in their club employment. The legendary Italian goalkeeper already played for 17 seasons at Juventus. This is sixth months more than the second ranked footballer, Sergio Pellissier (Chievo), and one year more than for Andrés Iniesta (Barcelona) and Roman Weidenfeller (Borussia Dortmund). The top 110 list is available in issue number 223 of the CIES Football Observatory Weekly Post.

In total, 61 footballers played for at least ten seasons in their current club. Among them are many other legendary players such as Lionel Messi (14 seasons in Barcelona’s first team squad), Giorgio Chiellini (13, Juventus), Sergio Ramos (13, Real Madrid), Michael Carrick (12, Manchester United), Marcelo (11.5, Real Madrid), Franck Ribéry (11, Bayern Munich), Marek Hamšík (11, Napoli), Fernando Torres (10, Atlético Madrid) and Cristiano Ronaldo (9, Real Madrid).

In five clubs, the most loyal squad member only played there for four seasons: Fiorentina (Badelj), Crotone (Martella), Getafe (Guaita), Nice (Mendy, Pléa and Pouplin), as well as Caen (Vercoutre, Féret, da Silva and Bazile). The freshly published 34th edition of the CIES Football Observatory Monthly Report analyses the relationships between squad stability and success in 31 top division leagues of UEFA member associations.

The first CIES Football Observatory Monthly Report published in January 2015 studied club stability across Europe. Three years later, the thirty-fourth edition develops this issue by illustrating the value of long-term planning for football clubs. The indicator selected is the percentage of players recruited by their employer club since less than one year.

The study reveals that the best performing teams have much more stable squads than lesser competitive ones. Between 2009 and 2017, big-5 league champions had on average only about one in four new players as squad members. This proportion can be considered as an optimal balance to achieve success.

The Report also highlights the increasing instability of teams across Europe. On the 1st of October 2017, 44.9% of players were recruited during the year. This figure was only 36.7% in 2009. If this trend continues, footballers who have been with their employer club for more than one year will soon represent less than half of squad members.

To limit the growing instability, football’s governing bodies should act against the increasing financial gaps between teams both nationally and internationally. They should also combat corrupt practices at both transfer market and club management levels. It is also necessary to limit the speculation around players’ mobility, notably through a greater protection of training clubs, the enforcement of the third-party ownership ban and the reinforcement of the regulations regarding football intermediaries.

Barcelona and Real Madrid top the rankings for the longest average contract duration of first team squad members. Six out of the eight top ranked clubs are still competing in European Cups. This illustrates the relationships between long-term planning and success. The 222nd edition of the CIES Football Observatory Weekly Post presents the data for all big-5 league teams.

On average, a Barcelona first team squad member has 3.23 years of contract remaining. This figure is 3.59 for the 11 players who have been fielded the most in domestic league games so far this year. The longest average contract durations for the other big-5 leagues were measured for  Tottenham , LOSC Lille, RB Leipzig and AS Rome.

At the opposite end of the table, the lowest figure overall was observed for the French side Amiens (0.99 years). In three clubs only, the average contract duration of the 11 most fielded players is below one year: Crotone, Benevento and Strasbourg. All the teams at the bottom of the rankings are confronted with the difficulty of renovating their squads without losing competitiveness.
