Live updates on transfer rumours.
TransferFeed valuation based on market analysis.
Recent reports from December 2025 mention CIES data suggesting a value between €41-48 million, an estimated release fee between €30-40 million, and market values from Transfermarkt and other sources at €28 million and €25.8 million. In November 2025, Genk reportedly hoped for a fee over €30 million. Earlier in 2025, reports consistently cited a release clause of either €40 million or £35 million (~€41 million). An Arsenal offer was reportedly structured to reach €45 million with bonuses (June 2025), and a separate report claimed a deal was almost done for £38 million (~€45 million) in the summer of 2025. Lower valuations from earlier in the year included a €15-20 million estimate (September 2025) and various Transfermarkt values that rose from €13 million (March 2025) to €23 million (November 2025).
Our valuation for Konstantinos Karetsas is driven by multiple, consistent reports of a release clause set by Genk at approximately €40-41 million (£35m). This figure is strongly supported by reports of a near-transfer to Arsenal for a similar amount (~€45m) and a potential offer from the same club that could rise to €45m with bonuses. The widespread, high-level interest from numerous top European clubs further solidifies this premium valuation.
