Gunnarsson told the club's official website: "It's a six-point game for us to be honest. They're below us, it's going to be the same against them as it was against Peterborough.
"Three points on Saturday was brilliant for us and we just have to kick on.
"We just had a stinker there (at Plymouth last season) but hopefully we'll be up for it on Saturday because we desperately need three points, especially playing against teams who are below us.
"They're struggling at the moment and they are going to be coming into that game the same as us, it's a six-pointer for them to get up there. It should be a good game."
