West Ham have signed midfielder Pierre Ekwah on a three year deal with an option for another one year.
Ekwah, 19, joins the Hammers from fellow London side Chelsea where he featured for the Under 23 side in Premier League 2.
The bidding midfielder will have preseason with the West Ham senior team as he hopes to cement a place in the Premier League squad for next season.
Born in the French city of Massy to Ghanaian parents, Ekwah has represented the European nation at Under 16 level.
Academy Manager Ricky Martin explained: “Pierre was identified by our recruitment department as a potential new addition for the U23s squad.
“We had an opportunity to assess him at the end of last season and, following that, we’re really happy to offer Pierre a new opportunity at West Ham with this contract.
“Everyone here wishes him a very successful career in East London.”
