Joeri Heerkens

In July 2025, reports detailed the transfer from Sparta Praha to Ajax for a confirmed fixed fee of €2 million. The deal reportedly also included a maximum of €1.5 million in potential bonuses and a ten percent sell-on clause. More recent reports from May 2026 suggest Ajax is considering a loan for the player to gain experience.

Our valuation for Joeri Heerkens is driven by his confirmed transfer to Ajax in July 2025 for a €2 million fee, which could rise to €3.5 million with bonuses. As a young goalkeeper on a long-term contract, his value is anchored to this recent transaction. The potential loan move reported in May 2026 indicates he is still developing, suggesting his current value is likely above the base fee but has not yet reached the maximum potential value.
