Since the start of July and the launching of the brand new player ratings service, the number of pages visited on the CIES Football Observatory website was multiplied by six. This exclusive tool notably provides the most reliable estimation of the transfer value of big-5 league players currently available on the market.

The ratings module also presents the exclusive CIES Football Observatory performance index for big-5 league players, as well as data on footballers’ career paths such as, among others, experience level compared to other players and transfer fees generated over the career.

The CIES Football Observatory has extended its online offering by launching a ratings module with exclusive statistics on big-5 league players. The new resource includes indicators such as transfer value, pitch performance and level of experience.

Dr Raffaele Poli, head of the CIES Football Observatory, said, “this development is a crucial step towards our recognition as the global leader in the scientific assessment of the transfer value of professional footballers. The tool will allow us to further highlight the accuracy of the algorithm developed”.

All things being equal, a wealthier club will have to invest more to sign a player. As a result, the transfer values published refer to the fee corresponding to the type of team most likely to be interested in recruiting the player. The specific price per recruiter club is only available on a consultancy basis.

Users have the possibility to give their opinion by indicating if the transfer value estimated by the exclusive CIES Football Observatory algorithm is lower, equal or greater than the real market price.

The ratings module also presents the sporting level of big-5 league players by means of an index taking into account performances achieved during the last 1,000 domestic league minutes in six areas of the game: rigour, recovery, distribution, take on, chance creation and shooting.

Finally, the new service includes data on the career path of a player and notably the number of league matches played at adult level. The level of experience of each player is then compared to the average measured at the same age for big-5 league footballers of the same position.

According to the CIES Football Observatory exclusive algorithm, the transfer value of players in the English squad amounts to €751 million. This figures is over €500 million for four other teams: France (€697 million), Spain (€639 million), Germany (€601 million) and Belgium (€550 million). Issue number 153 of the Weekly Post presents the data for all nations.

The total transfer value of twelve participating teams out of 24 is lower than that of the most expensive player overall: Cristiano Ronaldo (€138 million). At the bottom of the table is Hungary (€30 million), ahead of Romania (€51 million), Albania (€57 million) and Slovakia (€59 million).

Issue number 152 of the Weekly Post presents the top 100 list of the big-5 league players with the highest transfer values. A calculator for footballers in the five major European leagues is available on the CIES Football Observatory website.

Who are the footballers whose transfer value is above €100 million? Issue number 152 of the Weekly Post unveils the excusive CIES Football Observatory list of the 100 big-5 league players with the highest values from a transfer fee perspective. Besides Lionel Messi, seven other footballers currently have a transfer value of more than €100 million.

According to the CIES Football Observatory algorithm, the players whose transfer could be negotiated at more than €100 million are Messi, Neymar, Ronaldo, Griezmann, Kane, Martial, Suárez and Dybala. More information on the criteria taken into account and the methodology used is provided in the 16th edition of the Monthly Report.

Since 2013, the correlation between the transfer values predicted by the CIES Football Observatory’s algorithm and the fees actually paid for the recruitment of big-5 league players has been close to 80%. The strength of this correlation shows that, on one hand, the footballers’ transfer market is rational and, on the other, that its rationality has been well understood by the econometric model developed.

Per position, the most expensive players from a transfer fee standpoint are Thibault Courtois among goalkeepers (€48.4 million), David Alaba among centre backs (€48.8 million), Hector Bellerín among full backs (€55.6 million), Paul Pogba among central midfielders (€90.4 million), Eden Hazard among attacking midfielders (€78.3 million) and Lionel Messi among forwards (€211.1 million).

The 16th Monthly Report of the CIES Football Observatory also presents the big-5 league players with the highest probability to be transferred for a sum of money. Among footballers with a transfer value of more than €25 million, the most likely to change team during next summer are Gonzalo Higuaín (€60.9 million), Alexandre Lacazette (€41.5 million), Michy Batshuayi (€25.2 million), Antoine Griezmann (€120.2 million) and Romelu Lukaku (€58.1 million).

Issue number 151 of the CIES Football Observatory Weekly Post ranks big-5 league clubs according to the average transfer cost per player fielded. Leicester City was crowned despite the third lowest transfer expenditure at English Premier League level (€2.7 million per player). Conversely, Newcastle United could not avoid relegation despite having on average played with the 8th costliest line-up (€7.9 million per player).

In the four other major European championships, the most positive and negative gaps between the position in the transfer cost ranking and that achieved in the final table were measured for Las Palmas (+6) and Valencia (-9) in Spain; Angers (+8) and Marseille (-10) in France; Mainz (+10) and Hannover (-9) in Germany; as well as for Empoli (+7) and Palermo (-5) in Italy.

Overall, the team who fielded on average the most expensive line-up was Real Madrid (€32.2 million per player), followed by Manchester City (€27.5 million), Paris St-Germain (€27.0 million), Manchester United (€26.8 million) and Barcelona (€23.7 million). Champions League finalist Atlético Madrid ranks only 13th (€8.8 million).
