West Ham boss David Moyes is wary going to Sheffield United.
Moyes admits he has a lot of respect for Blades boss Chris Wilder.
He said, "We're looking forward to playing the game against Sheffield United. We're going to be travelling up to Sheffield and we're looking forward to it.
"We were disappointed with Tuesday [away at Bristol City] but we're getting on. We're getting ready for the next game and want to be as prepared as possible. We're back at it and hopefully we're ready for the game.
"Chris Wilder has always done a really good job. He's won a couple of Manager of the Year awards due to the level of work he's done at Sheffield United, and he's got a great history there.
"He's back after a spell out and his teams have always been really hard to play against. He always had hard-working teams, and we know we're in for a difficult game in a good atmosphere at Bramall Lane."
