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.


Job done: the Bayer 04 eSports team defeated SV Darmstadt 98 in the play-offs to secure their consecutive participation in the VBL Club Championship final. The journey continues now for Leverkusen on Saturday 7 March (from 17:00 CET) with a last-16 encounter at Hamburger SV.

And one young man in particular will not forget this game in a hurry. The Werkself review.

The Black and Reds kept their opponents away from their goal for the best part of 90 minutes.

Bayer 04 can go through to the Round of 16 of the UEFA Champions League for the ninth time tonight, 24 February (kick-off: 21:00 CET) and be in the top 16 clubs in Europe. A good omen: Leverkusen have progressed to the next round after winning the first leg in 20 of their 22 knockout rounds in European competitions to date. For their part, Greek record champions Olympiacos rested several players for last weekend’s league fixture ahead of the play-off second leg at the BayArena and will now do everything in their power to turn the tide with their usual aggressive and high pressing. The discussions on Werkself radio are likely to be just as intense as the battle on the pitch, with commentator Florian Bechholz welcoming honorary captain Stefan Kießling and goalkeeper Mark Flekken.
