West Ham United are interested in signing 22-year-old Netherlands youth international Rav van den Berg from FC Koln. Everton and Serie A club Atalanta are also interested in the player. The Bundesliga club would prefer to keep the defender for at least one more season to increase his market value, but would be open to a sale for a bid of approximately €15-20 million. West Ham are considering signing a centre-back because of the uncertain futures of Jean-Clair Todibo and Konstantinos Mavropanos. West Ham have the financial capacity to meet Koln's valuation. Atalanta could use the prospect of European football to attract the player. Van den Berg joined Koln in August 2025 and has a contract that runs until 2030. He has 11 caps and one goal for the Netherlands U21s. According to Transfermarkt, his current market value is estimated to be €7.00m.
