"We're unbeaten in five, although there's probably a few too many draws there for us, and we need to try and turn them into wins," said Davies. "We're a lot more confident that we have been in recent weeks and we'll try and get a result on Sunday.
"I think we owe them up here because the last few seasons they've turned us over. Hopefully it will be one of those games to give everyone a massive lift so we can start climbing the table. I think Chelsea had a little dip and beating Valencia has probably given them a massive lift.
"But we've got to make it a difficult game for them.
"I don't think they will relish coming here. (Didier) Drogba is suspended so it's a good opportunity for us but we know that we've got to be somewhere near our best to get a result."
Nicolas Anelka, for his part, is doing as much as anyone to keep his manager in a job.
The France striker's second-half winner against Rabotnicki was his sixth goal of the season and confirmed the value of a player who signed a contract extension in August to commit his future to the club to 2011.
"He's deadly and his finishing is world class," said Davies.
"We're obviously delighted that he decided to stay and he's going to be a very important player for us."
