The Magpies manager admits that midfielder Yohan Cabaye's sale to Paris Saint-Germain disrupted his side as they slipped to a 10th-placed finish in the Premier League last season
The Magpies' poor form over the final period of 2013-14 saw them slip to 10th in the table, having been affected badly by Yohan Cabaye's sale to Paris Saint-Germain in January.
But after a summer which has seen him recruit the likes of Remy Cabella, Daryl Janmaat and Siem de Jong, Pardew feels that St James’s Park is back under control and is happy with hi s squad.
He told reporters: "The difference now is we're much more settled.

"We have a newfound sense of belief now and players grow when they see new signings. If you see more quality around, you feel more confident."
Asked if he needed any more signings, Pardew replied: "I don't think we're short of anything because, if I look at my roster, it's full up. I actually haven't got a spare place on the roster.
“Ideally, managers always want more players and more quality but I'm not going to bemoan where I'm at. We've got good strikers in the building, although I don't necessarily think that’s us in terms of the transfer market.
"It's not something we've completely given up on. We're still looking at it and we've got our finger on the pulse and that's something we've done very well this summer.
"I've nothing to moan about now in terms of what's happened this summer. We've got a strong squad – perhaps the biggest and best I've ever had in terms of options – so we're in a great position."
Pardew also hailed much-maligned owner Mike Ashley, whom he says has provided him with the support that has led the 53-year-old to be the current second-longest-serving manager in the Premier League.
"When I signed the new contract, Mike always knew there would be ups and downs for both of us," Pardew said ahead of Newcastle’s opener against Manchester City.
"He stood by me and this feels like an up time for me. He's armed me again. He's stood by me.
"It's that kind of relationship you can only hope for as a Premier League manager and I'm lucky enough to have it. I hope I can repay him this season."
