Peer Koopmeiners

In June 2026, reports claimed AZ Alkmaar's asking price is approximately €20 million. This followed several reports in May 2026 that valued him around €10 million, a figure also used by Transfermarkt. In March 2026, a hypothetical transfer was linked at approximately £10 million (around €12 million). Earlier, in January 2025, it was widely reported that AZ rejected a €10 million bid from FC Porto.

Our valuation for Peer Koopmeiners is shaped by conflicting but informative reports. The floor is established by a rejected €10 million bid from Porto in January 2025, while the ceiling is set by AZ Alkmaar's recently reported asking price of €20 million. Given his long contract until 2028 and interest from multiple clubs, we estimate a compromise fee is most likely.
