Hupu announced on May 6 that Torsten Rumpf, a reporter from the German media Bild, wrote a transfer column about Werder Bremen and Hamburg.
Karim Koulibaly, regarded as Werder Bremen's most dazzling star in recent years, is 18 years old. He made his 26th appearance in the game against Augsburg with a score of 1-3, thus becoming the youngest regular starter among all Bundesliga clubs this season. In just nine months, his value has soared from 1 million euros to 22 million euros, and is still rising.
Obviously, his outstanding performance has attracted a lot of attention, including Paris Saint-Germain, Chelsea, Newcastle United and other top European clubs.
Bremen is pleased that Coulibaly will bring considerable income to the club if he transfers to join this summer. However, the central defender who originally played in the youth training camp of the newly promoted club Hamburg in the 2023/24 season and then joined Werder Bremen on a free transfer made Hamburg dissatisfied.
However, if the Germany U21 international player finally completes the transfer, then Hamburg will not be left empty-handed this summer.
"Sports Bild" explained that in such a situation, Werder Bremen had already paid about 70,000 euros in youth training compensation to Hamburg. This amount is not very large and must be paid when the player registers as a professional player for the first time.
However, Hamburg will receive a share of the transfer fee. FIFA's regulations on player identity and transfer state in Article 8 (20): If a player transfers before the expiration of his contract, all clubs that have contributed to his youth training and development will receive part of the compensation paid to his original club (that is, solidarity contribution).
The youth training period is defined as the stage from 12 to 23 years old. The relevant clubs have the right to obtain up to 5% of the transfer fee.
This means that Hamburg, they have the right to obtain a certain share, so they will get a windfall. His time in Hamburg will be counted as six years of youth training. Bremen hopes to receive at least 30 million euros in transfer fees from Koulibaly, which means Hamburg will receive about 600,000 euros.
At the same time, after a year in the U19 youth team, Koulibaly made his first appearance for the Werder Bremen first team in the summer of 2025, becoming the most popular rising star since Brazilian genius midfielder Diego (41 years old).
In 2009, Bremen sold him to Juventus for 27 million euros. This transaction is still a record transfer fee in the history of Werder Bremen.
