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.


Rüdiger Vollborn has been at the club for 40 years, he holds the record number of Bundesliga appearances for the club (401) and is the only Bayer 04 player to have won both the UEFA Cup (1988) and the DFB Pokal (1993). And the Berliner stayed with the Werkself after ending his impressive playing career as he worked as a goalkeeping coach for the following nine years. Vollborn now works under the Bayer Cross as a fan liaison officer and club archivist. Since February 2021, the personalised Black and Red lexicon takes Werkself fans under the heading of 'Rudi recounts...' on a brief trip through the history of Bayer 04 every month.
