West Ham United got down to work under cloudy skies in Dubai on Friday morning.
Manager Slaven Bilic put his squad through their paces in warm but gloomy conditions in the Emirate - the Hammers' second training session since arriving in the Middle East on Thursday morning.
Arthur Masuaku and Sam Byram were in action after returning from injury, while new boys Jose Fonte and Robert Snodgrass continued their integration into the squad.
West Ham will return to England on Monday to complete their preparations for the Premier League trip to Watford on Saturday 25 February.
