West Ham have snapped up teenage forward Thierry Nevers from Reading on a three-year contract, with the option of a further year.
The 19-year-old will complete the move, for an undisclosed fee, on June 9 when the summer transfer window opens.
Nevers had not made a first-team appearance for Reading but scored nine goals in 25 games for their under-23 side.
He will initially link up with West Ham's under-23s at their Chadwell Heath base and joins after nine years with his boyhood club in Berkshire.
Nevers told the club website: 'I'm very excited to join West Ham United.
