Peer Koopmeiners

In summer 2026, reports detailed extensive negotiations. Club Brugge reportedly had bids of €9M plus €2M in bonuses and a separate €13M offer rejected by AZ. AZ's asking price was cited inconsistently, ranging from €12-14M up to a firm €17M. During the same period, Bologna was linked with a €10M offer, while AZ's valuation for Italian clubs was reported as high as €18-20M. Earlier, a hypothetical transfer to Celtic in March 2026 was valued at approximately £10M (around €12M), and reports from January 2025 mentioned a rejected €10M bid from FC Porto. His Transfermarkt value was cited as €10M and €12M during 2026.

Our valuation is driven by the intense transfer negotiations for Peer Koopmeiners during the summer of 2026. Multiple reports confirm AZ rejected bids up to €13 million from Club Brugge, while consistently demanding a fee between €15 million and €17 million. The final estimate reflects a likely compromise point between the highest rejected offer and the club's firm asking price.
