Stefan Posch

The most recent transfer rumour from June 2026 suggests a potential fee for a permanent move to Mainz in the 'mid to high single-digit million' Euro range. This follows Como officially completing a mandatory buyout from Bologna for €5.5 million in January 2026, which was part of an initial loan deal from September 2025 that included a €500,000 loan fee. In the summer of 2025, Atalanta reportedly declined an €8 million purchase option, and Bologna's asking price for other clubs was reported to be around €5 million. Earlier, in February 2025, Como was linked with offers between €7 million and €8 million. His market value was reported by Transfermarkt as €5.5 million in April 2026.

Our valuation is driven by the most recent reports from June 2026 indicating FSV Mainz 05 is in concrete talks for a permanent transfer of Stefan Posch for a fee in the 'mid to high single-digit million' Euro range. This is strongly supported by the recent history, specifically Como's mandatory buyout of the player from Bologna for €5.5 million in January 2026. His successful loan spell at Mainz likely justifies a value above that recent buyout figure.
