West Ham are ready to step up their interest in Fulham defender Tosin Adarabioyo.
The stopper comes off contract at the end of the season.
The Guardian says West Ham are entering the tug-of-war for Adarabioyo's signature.
Nayef Aguerd can be sold this summer, while Kurt Zouma has had physical problems. West Ham want another centre-back as Angelo Ogbonna is also coming off contract.
The Irons showed an interest in Max Kilman in January, but Wolves did not want to sell their captain.
