While the overall financial package presented was undeniably attractive, the specific structure of the proposed deal ultimately led to the breakdown of negotiations. Reports suggest that Dortmund’s initial transfer fee was approximately €46 million.
With the inclusion of various performance-related bonuses, the total valuation would have slightly surpassed Cologne’s €50 million asking price, potentially reaching between €52 million and €53 million. However, Cologne expressed significant dissatisfaction with the stringent conditions attached to these potential incentives.
The proposed bonuses were structured over an exceptionally long timeframe and were heavily contingent on the player achieving a substantial number of first-team appearances, meaning Cologne lacked any genuine financial assurance.
