The Reds beat local rivals Everton 4-0 on Tuesday to strengthen their grip on fourth place in the Premier League, but the Wales international insists that they won't be taking the trip to the Baggies for granted.
He told the club's official website: "From a motivational point of view, those big derby matches can take care of themselves but I don't think that's a big issue in this changing room and we treat every game the same.
"At other clubs it might be, but the type of personalities and characters we have and the hunger the players have to really achieve something this season means you never feel people are going to be complacent or take their foot off the pedal.
"I think everyone knows the massive aim and task we've got on our hands this season. We appreciate that things change every week in the Premier League, so every game is just as important. We are looking to keep this momentum going and hopefully we can get three more points at the weekend."
The Reds beat West Brom 4-1 at Anfield earlier in the season.
