Grady Diangana today joins Albion on a season-long loan from West Ham United.
The 21-year-old, who will wear the No.29 shirt with “Diang” on the back, made 21 appearances for the London Stadium outfit last term, scoring twice.
The Congolese-born attacking midfielder, who has represented England alongside Kyle Edwards at youth level, signed his first professional contract while Baggies boss Slaven Bilić was at the Hammers helm.
Diangana is Albion’s sixth signing of the summer window following the recruitment of Filip Krovinović, Kenneth Zohore, Semi Ajayi, Darnell Furlong and Romaine Sawyers.
Sporting and Technical Director Luke Dowling said: “Grady comes with good Premier League experience but he’s now at this early stage of his career where he needs to get good, regular game time.
“He is direct with his running, has good ability and will be another exciting addition to our squad.”
