West Ham boss Slaven Bilic says their Dubai training camp will be good for his players.
He wrote for the London Evening Standard: "We flew there overnight after training at the London Stadium and meeting many young fans.
"It was great to see around 10,000 turn up for the Family Fun Day.
"It is the first time I have taken a squad away in this manner but it is common over here.
"We are going there to train first of all and we will work harder than if we had stayed here.
"We will train in the morning, have lunch together and then the players will have some free time to recharge the batteries in a good and decent way."
