West Ham boss David Moyes says Leeds will be a test for his team, but says they go to West Yorkshire confident after their recent run of wins.
"We're going to have to play well and show that we have players with a similar type of energy as Leeds do as well," says the Scot.
"We want to win as many games as we can and this is another opportunity. It's a tough game but we're in good fettle.
"Our players know their jobs and we have lots of players playing well at the moment, but we go there knowing we're up against an interesting and good team."
