Southampton's Jay Rodriguez in action with Liverpool's Joel Matip and Nathaniel Clyne
The Reds will be hot favourites ahead of the meeting with David Moyes's side, but Matip is wary of being on the end of a potential upset from the Black Cats.
The defender told the Liverpool Echo: “There are no small clubs in the Premier League.
“Every team has a lot of quality.
“You can’t just go out, take it easy, collect the points and go home. You have to work hard every game and do your job. You have to earn it.”
Sunderland were without a win in their opening 10 Premier League games but have recently managed to breathe new life into their campaign following back-to-back wins against Bournemouth and Hull City and will travel to Anfield with a degree of confidence despite sitting second from bottom in the league table.

Liverpool have been excellent at home so far this season, with only Manchester United managing to keep them at bay and leave Anfield with a point - while the Reds have handsomely overcome Leicester City, Hull City and Watford their own patch this season, as well as beating West Bromwich Albion.
The Reds are just one point off the top of the table and will look to keep up the pressure on Chelsea if they are unable to overtake them at the summit. They will be keen to put down a marker ahead of Chelsea's game with Tottenham but Sunderland will feel they have an element of freedom going into the game, and will be keen to build on recent wins.
