The Spaniard is confident the Gunners can show an improved performance from their 5-1 drubbing on Merseyside last December.
Asked if we wanted to prevent the same result, Emery said: "Each match, each moment, each season is different. We can use last year, two years ago, three years ago, four years ago.
"But really it's about our moment and this moment. Anfield is a big atmosphere with their supporters, they are a very good team and they advantage for us in their progress and in the last years.
"In Anfield they have one step more in feeling strong, but it's not for us, it's for all.
"We need to take our best performance and to go there with a good feeling and also thinking we can achieve that performance individually and collectively to be strong and to have our chances. We are looking forward to going there and showing that."
