West Ham caretaker boss Kevin Keen says new signings Walter Lopez and David Di Michele have impressed in training.
Keen told whufc.com: "I have been really impressed this week with the attitude and the tempo in training and the football that has been played. Walter has done well. He likes to get forward from left-back and David is showing he will be the type of creative centre-forward that the crowd will enjoy watching.
"I have tried to make training upbeat and up-tempo. I want players to enjoy training and hopefully that is what has come over and we are looking forward to Saturday. The players want to keep our good start to the season going."
