West Ham captain Mark Noble says manager David Moyes' arrival has seen training intensify.
Noble insists the squad have stepped things up before their first game under Moyes' control against Watford on Sunday.
"It has been really good working under the new manager David Moyes and his coaching team," the captain told West Ham's website.
“When a new manager comes in, the intensity goes up straight away because all the players are playing for a place in the team.
“Obviously, every manager is different and does things in different ways, and the boys have enjoyed training, doing different activities in the sessions he has put on.
“I have played under quite a few different managers now and you get used to their ways really quickly. Every manager has different ideas and different ways of playing and we have got to get used to them as quickly as possible as the games come thick and fast, especially in December."
