He said: "I want it to be a great game and I want to make sure we do the best for our fans.
"We'll have good travelling support and it's important that they have a good night.
"We go there well equipped, we know what we are doing and we know our gameplan. We will attack the game and look to win it on the night.
"We have been to Merseyside before and won and we love going there.
"They are really good footballing people who know their stuff."
