Previously, CIES Football Observatory, a Swiss football research institute, listed data on its use of its own youth players in the world's top 60 leagues. A few days ago, they made another statistic listing the 100 most profitable academy teams in the world in the past 10 years. Players who are between the ages of 15 and 21 and have played for at least three seasons are counted.
20th place: Liverpool
Revenue: 199 million euros
最高收入的转会:斯特林(Raheem Sterling)
Sterling came through the youth team of London side Queens Park Rangers, switched to Liverpool at the age of 15, debuted in the Premier League two years later at the age of 17, became the most valuable young player in Europe at the time in 2015, and moved to Manchester City for 63.7 million euros in the same year, becoming the most expensive English player in history.
No. 19: Aston Villa
Revenue: 203 million euros
最高收入的转会：杰克·格里利什（Jack Grealish）
Jack Grealish arrived at Aston Villa at the age of six, made his first team debut at the age of 19 in May 2014 and was appointed captain in 2018 at the age of 23.
In the 19/20 season, he led Villa to the Premier League as captain, and in the second season, he handed over 6 goals and 12 assists, once putting Villa in the top four, plus playing well in Euro 2021, Manchester City immediately did not hesitate to take him under his banner for 117 million euros, breaking the record British transfer fee for Manchester United's 89 million pounds to buy Pogba five years ago, contributing more than half of the 203 million euros in revenue.
18th place: Paris Saint-Germain
Revenue: 212 million euros
最高收入的转会：阿诺·卡利穆恩多（Arnaud Kalimuendo）
Although PSG is "washy", they have a first-class academy, and the transfer of Liverpool's Mamadou Sako, Juventus's Rabiot, Bayern's Kingsley Koeman, and Chelsea's Christopher Nkunku are all from this giant's academy. But none of these youth players are the one with the highest transfer fee, but Arnold Kalimundo, who is only 20 years old, and I believe that there are not many fans who know him. Arnold Kalimundo arrived at the Paris Saint-Germain training centre at the age of 11 and played in the youth league under Thiago Motta, where the striker was excellent in his shooting skills and showed great composure in front of goal. In 10 games in two seasons in the UEFA Youth League, Arnold Kalimundo scored nine goals, including a brace against Liverpool and a hat-trick against Real Madrid. His performances led him to sign his first professional contract in the summer of 2019. Without much opportunity in Paris, he moved to Ligue 1 Rennes for €20 million in the summer transfer window, breaking Nkunku's record of €19.5 million when he moved to RB Leipzig in 2019.
No. 17: Bayer Leverkusen
Revenue: 214 million euros
Highest paid transfer: Kai Havertz
Kai Havertz is again linked to him as a striker or midfielder, but at Bayer Leverkusen, that ambiguity has allowed him to play well. Kai Havertz, who joined Bayer Leverkusen's youth team at the age of 10, won the league title (Under-17) at the age of 17 and scored 17 goals in 34 league games in the 18/19 season, an average of one goal per two games, and finished runners-up in Germany's Footballer of the Year award at the age of 20. The following season, he continued to score in double figures in the league and became the youngest player to make 100 appearances in the Bundesliga. It attracted a lot of interest from Chelsea, who were in desperate need of a rebuild, and the €80 million deal made him the second most expensive signing for Chelsea after Kepa.
The back waves of the Yangtze River push the front waves, and the pharmaceutical company produces a "new Kai Havertz", Florian Wirtz has been rated as the new hope of the German national team in the first season of his debut, but unfortunately he suffered a major injury at the beginning of his debut and was reimbursed for the season. After his comeback, he returned to the field with a stronger attitude, and led the team to the league championship this season, still unbeaten for the time being, leading Bayern Munich with a four-point advantage, and if he finally won the Bundesliga title, his value will definitely climb up the ladder and break the record held by Kai Havertz.
16th place: Real Sociedad
Revenue: 218 million euros
最高收入的转会:阿尔瓦罗·奥德里奥索拉(Álvaro Odriozola)、伊利亚拉(Asier Illarramendi)、伊尼戈·马丁内斯(Iñigo Martínez)
Real Sociedad's first was divided between three people, all with a transfer fee of 32 million euros, namely Álvaro Odriosola, Iliara and Inigo Martinez, the former two had a very similar path, joining Real Madrid in 2018 and 2013 respectively, the former was bought as Daniel Carvajal's deputy, and the latter was known as the "new Xavi Alonso" that year, replacing the "real Xavi Alonso". Unfortunately, neither of them was able to establish themselves at Real Madrid and eventually returned to play for their old clubs. Interestingly, Illara returned in 2015 at half price of 16 million euros, breaking the record for Real Sociedad at the time.
Inigo Martinez's transfer benefited from Laporte's high price poached by Manchester City, Bilbao earned a transfer fee of 65 million euros from him, and then bought Inigo Martinez for 32 million euros after the neighbor Real Sociedad, breaking the team's transfer record and maintaining it to this day.
