The Magpies are currently 14th in the overall standings and have only won once in their last 10 games in all competitions, 3-0 at home over strugglers Wigan earlier this month.
They welcome the defending champions to St James' Park on Saturday, but Pardew is not fearing Roberto Mancini's side, who have only triumphed once in their last six games across all competitions.
Pardew admits last weekend's derby defeat by rivals Manchester United will have fired up City, but he does not think they post the same threat as they did last term.
"They were definitely the best away team we played last season," Pardew said.
"When they were at home last year they were pretty awesome and we didn't really get a foothold in that game.
"What I do know is they will be pretty much focussed on this game and therefore it probably makes it a shade more difficult. But when you're champions of the Premier League, it's a difficult game full stop.
"We got nothing off them last year but I don't think they are as strong as they were last year coming into this game.
"We are having a tough run, we don't disguise that, but the work ethic is there. One big result, which could happen this weekend, could change a lot of the picture and we could find ourselves in a good position in the league."
