The background to the ban is a dispute between Hakan Calhanoglu and the Turkish club Trabzonspor. During his time at Karlsruhe SC in 2011 Calhanoglu, as a minor, reached agreement with Trabzonspor regarding a transfer. However, he extended his contract at Karlsruhe SC and later joined Hamburg SV. The CAS agreed with FIFA that the actions of the player represented a breach of contract with Trabzonspor.
Bayer 04 Leverkusen were not involved in the proceedings as the player signed for the Bayer 04 Leverkusen several years after the incident. "Of course, we regret this decision which is completely incomprehensible for us," said sporting director Rudi Völler. "It's a heavy blow for Hakan but also for us. We’re also being heavily punished although Bayer 04 Leverkusen had nothing to do with the events in 2011. We are now missing a very important player in a crucial phase of the season."
Bayer 04 CEO Michael Schade also criticised the verdict. "In addition to the player, it also affects the club that played absolutely no part in the events of the time. Unfortunately we are left with no alternative but to accept the decision," said Schade.


Bayer 04 Leverkusen have loaned U19 midfielder Jeremiah Mensah to Dutch second-tier side Roda JC Kerkrade for one year. The 18-year-old Germany youth international has a long-term contract at the club to 2031.

Villa Fiorito, River Plate, Ligue 1, the World Cup final and now Bayer 04: Facundo Medina’s life story so far has been shaped by special places, clubs, matches and names. One of them is Diego Maradona, who, like Medina, hailed from the south of Buenos Aires. Another is Exequiel Palacios, his former team-mate at River Plate, who was raving about Bayer 04 to him as recently as the World Cup in North America. Medina has now taken the plunge into the Bundesliga and, as an Argentine World Cup runner-up, has joined Bayer 04 from Olympique de Marseille this week. It is set to be the next successful chapter in his career. Leverkusen’s new number 2 brings with him a South American mentality and passion, a wealth of experience from many years in Ligue 1, and a fascinating story to the Rhineland – and to a club where the 1.84-metre-tall left-footed player will be reunited with Palacios and several other familiar faces.
