Live updates on transfer rumours.
TransferFeed valuation based on market analysis.
In May 2026, reports indicated that FC Köln was exercising its purchase option for a fee of either €2 million or €3.2 million. This followed earlier reports from March 2026 stating the deal included a purchase obligation of over €3.2 million. When the initial loan from Mainz to Köln was arranged in July 2025, the purchase obligation was reportedly set at approximately €3.5 million. At that time, general interest from multiple clubs was linked to a potential fee of over €4 million. For historical context, a previous potential deal with Schalke was mentioned at €5 million plus bonuses, and his completed transfer from RB Leipzig to FSV Mainz 05 in July 2023 was for a fee of €5.0 million.
Our valuation for Tom Krauß is driven by the consistent reports surrounding his loan-to-permanent move from Mainz to Köln. The available data points to a purchase obligation or option valued between €3.2 million and €3.5 million, which is slightly below the initial reported asking price of over €4 million in summer 2025 and his €5 million transfer in July 2023. The most recent reports confirm a final fee of €3.2 million, which we consider the most likely value.
