West Ham United's players continued their preparations for Sunday's home Premier League derby with Chelsea by training at London Stadium on Friday.
David Moyes put his squad through their paces as the Hammers get set for their first game on home turf since lifting the UEFA Europa Conference League trophy in Prague in June.
New signings James Ward-Prowse and Edson Álvarez tested out the London Stadium pitch for the first time and both could be involved when the Blues come to town.
