Early professional experience is key to succeed in football. Great discrepancies exist between clubs and leagues in the opportunities given to young players to prove their talent. Issue number 294 of the CIES Football Observatory Weekly Post presents the percentage of minutes played in the current season or the last completed one by U21 footballers from 1,292 clubs and 93 top divisions worldwide.

At league level, the playing time of U21 footballers stretches from 29.0% in the Slovakian Super Liga to only 3.7% in the Saudi Pro League and the Turkish Süper Lig. In South America, the figures vary from 21.2% in Uruguay to 11.0% in the Argentina. The French Ligue 1 is the major European league with the highest percentage of minutes by U21 players (15.0%), while the Spanish Liga is at the opposite end of the table (7.0%).

Between January 2015 and December 2019, Red Star Belgrade won 130 domestic league matches out of the 135 during which they scored the first goal: 96.3%.

The full analysis is available in the 293rd CIES Football Observatory Weekly Post.

Per league, the lowest value were recorded for Toulouse, Augsburg, Udinese, Eibar and Southampton. The lowest percentage overall was recorded for the Australian side Central Coast Mariners (20 wins out of 53, 38%).

At league level, the values range from four fifth of wins for the team having scored the first goal in the Moldavian top division to only about two thirds in the Chilean one. The average for the 92 competitions analysed is just below 70%. At the level of the big-5, the percentages go from 71.1% in the English Premier League to 67.8% in the German Bundesliga. The lowest values in Europe were recorded for the Belgian and Norwegian top divisions (66.3% in both cases).

Issue number 292 of the CIES Football Observatory Weekly Post ranks countries worldwide according to the number of their representatives having played professional football abroad during the calendar year 2019. Brazil is at the top of the table (1,600 players, of which 74.6% active in top division leagues) ahead of France (1,027, 74.0%) and Argentina (972, 75.5%).

In total, 186 national associations had at least one player expatriated in the 141 leagues from 93 countries included in the sample. However, altogether, Brazil, France and Argentina provided up to almost one quarter of the total foreign workforce in global football (22.5%). Nigeria is the main African exporting nation (399 players abroad), while Japan is the principal Asian one (161).

The CIES Football Observatory Atlas of Migration presents the main destinations for each origin. This exclusive tool notably reveals that Portugal is by far the main destination for Brazilians, ahead of Italy and Japan. The three main destinations for the French expatriates are England, Belgium and Luxembourg, while those of the Argentineans are Chile, Mexico and Spain.

The 291st Weekly Post of the CIES Football Observatory highlights the main clubs from where current big-5 league players departed to reach the five major European leagues. At the top of the stepping-stone club rankings are three regular European Cup participants: AFC Ajax (22 players currently in the big-5 were recruited there), SL Benfica (21) and RB Salzburg (20).

In the top 15 positions also are three Belgian teams (KRC Genk, RSC Anderlecht and Club Brugge KV), two further Portuguese clubs (Sporting Clube de Portugal and FC Porto), an additional Dutch one (PSV Eindhoven), as well Swiss (FC Basel), Croatian (Dinamo Zagreb) and Danish (FC København) sides. The B-teams of Real Madrid (4th) and FC Barcelona (11th) also figure high in the rankings. The first non-European team is Boca Juniors (15th).

The 54th edition of the CIES Football Observatory Monthly Report broadens the analysis by revealing that recruitment from a non-big-5 league team is the most common way of entering the five major European leagues (48%), followed by advancement from the youth academy or the B-team of a big-5 league club (39%, up to 50% for players who made their debut in the Spanish Liga) and the promotion from a second division of the club of belonging (13%).

The 290th edition of the CIES Football Observatory Weekly Post ranks clubs from 87 top divisions worldwide according to the number of players fielded in domestic league matches since January 2015. The highest value was recorded for the Colombian side of Deportivo Pasto (176 different players), while the lowest one was measured for Shanghai SIPG in China (44 players).

South American clubs are over-represented among those with the highest squad turnover: 7 in the top 10 positions and 14 in the top 20. Conversely, many top-flight European teams are among those who fielded the least different players in domestic league matches since January 2015, such as Manchester City (52), Real Madrid (54) and Bayern Munich (59).

Generally speaking, the richest leagues are not those where clubs change the most players. The average number of players fielded per club and season varies between 38.7 in the Paraguayan top division and 22.1 in the San Marino one. The highest values in Europe were recorded in Romania (30.5 players per club and season) and Croatia (30.2).
