Alan Pardew believes an extended FA Cup run can breed a "winning mentality" to boost Crystal Palace's Premier League relegation battle.
New boss Pardew took charge of Palace for the first time after leaving Newcastle in Sunday's 4-0 third-round FA Cup victory at Conference club Dover.
Newcastle owner Mike Ashley refused to view cup progress as a priority during Pardew's four years on Tyneside, but the former Eagles midfielder is now keen for Palace to fight on all fronts.
Pardew postponed talk of his Newcastle exit "for another day" in the wake of Palace's routine cup win, where Scott Dan headed a brace and Dwight Gayle and Kevin Doyle also found the net.
"I said to the players that an FA Cup run gives confidence and it breeds a winning mentality," said Pardew.
"And it was important that we won the game.
"So we're in the hat and, like in any cup competition, if you're in it, you can win it."
Pardew attempted to hold his tongue on all matters Newcastle after just 48 hours in the Selhurst Park hotseat, but his cup ambitions indicate his true feelings on the Magpies' recent pragmatism.
Newcastle won just one FA Cup match in their four years under Pardew, with owner Ashley's focus on the Premier League revealed at a May 2014 board meeting.
Supporters on Tyneside were often left frustrated by a perceived lack of ambition, while Pardew generally kept his counsel on the matter.
Pardew refused to answer questions on his warm Palace welcome after an uneasy ride from Newcastle supporters.
The former West Ham manager did, however, hint he would address his Newcastle departure ahead of Palace's Premier League clash with Tottenham on January 10.
The new Selhurst Park boss pledged to "put the ball at risk" and "have a go" as he bids to guide Palace out of the relegation zone to top-flight safety.
Palace's victory at Dover proved their first in nine matches in all competitions, that lowly record accounting for the departure of boss Neil Warnock.
The new boss believes favouring positive, attacking football will be vital to their chances of avoiding the drop.
"I'm going to promise the fans two things - one that we're going to put the ball at risk and two that we're going to have a go," said Pardew.
"I'm fortunate that they already have a special bond with me anyway, through my playing days here.
"But I've been on the other side of that support and that noise that they generate at Crystal Palace.
"Hopefully that will keep them in that frame of mind that they are at the moment until the end of the year, because we won't go up, or stay up, without them.
"I really did change my formation today, really and truly to say to the team, that we need to put the ball at risk.
"I was trying to get the message to the team that we need to have a bit more attacking oomph, so to speak.
"We are not going to stay in the Premier League unless we express ourselves.
"Although Scott (Dann) will get the headlines for the two headed goals, actually he should get the headlines for his distribution from the back, which was excellent today."
