McAuley scored for the Baggies as they upset Liverpool during the last campaign, and the Northern Ireland international has insisted that he and his teammates are confident of repeating the feat on Saturday.
The 33-year-old told the Express & Star: "We need to go there and do it all again. They're flying this season and playing some good football so it's going to be a massive test for us.
"They're in their second year with Brendan Rodgers and they've now got a style and a flow about them.
"But we're gaining confidence ourselves and we're beginning to bed players in. We're getting some momentum and hopefully we can go there and cause an upset."
West Brom have yet to lose away from home in the Premier League this season.
