Development squad defender Pierre Ekwah-Elimby has departed the club and
joined West Ham. The Frenchman arrived at Chelsea in the summer of 2018
from Nantes and appeared for our Under-18s and 23s, signing his first
professional contract in January 2019. We would like to thank Pierre for
his contribution and wish him well for the future.
