Willum Thor Willumsson

The only explicit fee in the available data is the €4.0 million Birmingham City reportedly paid to Go Ahead Eagles for the player's transfer in July 2024. Subsequent transfer rumours from January 2026 mention interest from NEC but do not include any specific bids or valuations.

Our valuation is driven by the recent €4.0 million transfer of Willum Þór Willumsson to Birmingham City in July 2024. However, reports from January 2026 indicate his prospects at the club have diminished, leading us to estimate a lower current market value. The reported interest from NEC, contrasted with a rejection from Go Ahead Eagles, supports a valuation below his last transfer fee.
