This Monthly Report analyses the technical performance data collected by our partners OptaPro for the 2019 regular season of the Major League Soccer (MLS) of the United States and Canada. The study shows that the style of football played in the MLS differs from that of the five major European leagues in two principal aspects: the pressing on opponents and the aerial game.

This report turns its eye exclusively to Latin America. Based on the model of the annual study carried out since 2009 for 31 European leagues, it compares four top division Latin American championships from the point of view of the demographic characteristics of players: the Brazilian Serie A, the Argentinean Superliga, the Chilean Primera División and the Mexican Liga MX. The study covers 79 clubs and 2,015 footballers

The 50th Monthly Report of the CIES Football Observatory analyses the make-up of the 42 teams having always been present within the five major European leagues over the course of the decade 2010. Although money is more than ever a key factor, squad stability stemming from good strategic planning and the ability of clubs to get the best out of the talents trained in their youth academies remain crucial success criteria even in the today’s hyper-commercial and globalised environment

The 49th Monthly Report of the CIES Football Observatory analyses clubs from 31 European top divisions from the standpoint of the demographic characteristics of their players for the period from 2009 to 2019. Particularly noticeable between 2009 and 2018, the trend in the European labour market for footballers towards less stability and a greater international mobility has declined over the past year

The 48th Monthly Report of the CIES Football Observatory analyses the evolution of the number and characteristics of footballers having played on loan for teams of the five major European championships during the last decade. It notably shows that clubs from these leagues take more and more players on loan: from 2.62 per club and season between 2009 and 2014, to 3.09 between 2014 and 2019 (+18%). In 2018/2019, footballers on loan played a record number of minutes within the big-5: 11.5%.

Since its creation in 2005, the CIES Football Observatory has been monitoring the transfer of players through information published by clubs and the media. This Monthly Report analyses the sums paid in transfer indemnities by big-5 league teams, the clubs and championships who benefited from these investments, the net balance sheets for both teams and leagues, as well as inflation observed year by year since 2010.
