West Ham have entered talks to sign Corinthians winger Wesley Gassova.
The London Evening Standard says Hammers chief Tim Steidten is moving for Wesley this week.
They hope to get the jump on European rivals for the 19 year-old.
Corinthians want 30m to sell, though West Ham aim to talk that valuation down.
Wesley's registration is shared between Corinthians (70%) and his agents (30%).
