David Moyes insists West Ham United must attack Manchester City when the two sides meet on Wednesday.
The Hammers desperately need points as they look to lift themselves out of the relegation zone.
And Moyes does not want to see his players sit back against Pep Guardiola's side.
He said: "It's as big as it comes, isn't it? We've got Manchester City and then Liverpool in the next two games so let's not kid ourselves.
"But you have to play them twice, everyone has to play them twice. These are our two games the way the ball has come out and we get them together.
"We know they are hard, but then we will go and try to be difficult to play against, hard to beat, but in the same breath we know we've got to go there and try to pick up points as well so there's a balance between both."
