Koen Kostons

Recent transfer rumours from June 2026 mention two key figures. One report states PEC Zwolle is asking for around €3 million. Another report from the same period suggests that interested club Hearts would need to pay approximately €1.5 million to sign the player. No fee information was available in the data for his previous transfers.

Our valuation is driven by conflicting reports from June 2026 regarding interest from Hearts in Koen Kostons. The range is defined by PEC Zwolle's reported asking price of around €3 million at the high end and a suggested fee of approximately €1.5 million at the low end. With three years left on his contract, the selling club has a strong position, but the wide gap suggests a compromise figure is most likely.
