The Magpies' streak of four consecutive home wins was ended on Sunday by Manchester City who boosted their title hopes with a 2-0 victory on Tyneside.
However Perch is confident Newcastle can end their season on a high note away to Everton and secure European football for the Magpies for the first time since 2007.
"If we get the win and results go our way, we're still in with a chance," the defender told the club’s official website.
"If you'd said at the start of the season that we'd have one game to go and we'd be in with a chance of a Champions League place, we'd have taken it.
"We're going to prepare the right way. We'll prepare as if the other teams are going to get beat and hopefully go out and beat Everton."
The former Nottingham Forest man feels the club have made huge strides since last season and is delighted for the club and the fans of their achievements this campaign.
"The gaffer said in the dressing room, not many teams will get that reception after getting beat 2-0," revealed Perch.

"It just shows how far we've come since last year and that the fans really appreciate what the players have done this year. They wanted to show us their appreciation and we wanted to do the same back. It's a two way thing really."
Perch believes Manchester City will win the Premier League as he feels it will be a hard task for QPR to become the first team in the top flight to win at the Etihad Stadium this season.
However he admits Roberto Mancini’s side are deserved winners if they do win their first title since 1968 and not just because of the money they’ve spent.
He added: "You could see how strong they were today. We kept them out for most of the game and then towards the end of the game they were still strong, made substitutions and got the two goals that they needed.
"They've obviously got unlimited funds to bring players in. We're not that kind of club. I'd like to think we're a more tight-knit group than what they are but fair play to them, they're a great team.
"They have great individuals, a great manager and they fully deserve to win the league if they do go on to do that.
"I think it's going to be a tough ask for QPR to go there and get a result so I think you've just seen the champions of the Premier League."
