Emery says there's a "big motivation" to get something from Anfield on Saturday.
He said today, "It's a big challenge. Each match is a big challenge and each match is for us to prepare best as possible. The idea is to continue creating in our way and style. We need to be strong and also we can recover some players to be fit. I think we are closer to achieving everyone being ready to play, but we need some more time. For Saturday we are in a good spirit and our players are ready to play with big ambition to do something important.
"It's a big stadium with a big atmosphere and I want to play every match in our amazing stadium with our amazing supporters in our home. But we need to play away and face big teams with big supporters. I think the motivation for us is very big on Saturday.
"We are going to have some Arsenal supporters helping us and it's a big challenge. It's going to be a different game to Burnley because the team is different. They are going to demand different tactical issues, but we want to play and show how we are now. It's a big test to show their capacity and our capacity."
