Considering player valuation context

The user shared a Chinese news item regarding Fermín López's market value being updated by Transfermarkt, indicating a potential range between 70 million and 90 million euros. It sounds like they might want a summary, context, or even a brief news piece about this update. Since they didn't ask a specific question, I should clarify what they're looking for or provide a summary and some insights on the estimate's implications, explaining it's speculative in nature.
