Steve Brown's first game in charge of the reserves ended in disappointment on Tuesday night, as Hammers were beaten 4-1 by Fulham.
On a tough night at Craven Cottage, the visitors found themselves 4-0 down at half-time, but battled back after the break and grabbed a late consolation thanks to a strike from Jack Jeffery.
Hammers: Blackmore; Mears, N'gala, McCartney, Widdowson; Hales, Dailly, Collison, Reid; Jeffery, Cole. Subs: Stech, Fitzgerald, Harvey, Sears, Blackwell.
