PALACE make the short journey across south London to face Millwall tonight, in what should be a super-charged atmosphere.
The sides had to settle for a 2-2 draw at Selhurst back in October, which turned out to be Dougie Freedman's last game in charge of the Eagles, but if Palace are to guarantee a play-off place they will need to show lots of grit in this London derby.
All 2,200 tickets in the North Stand Upper Tier at the New Den have been snapped up and there will be no further tickets available to Palace supporters.
Both clubs are also advising not to travel to the stadium if you haven't got a ticket.
When it comes to recent game history, there have been five draws in the last nine clashes since 2003, with Palace's last defeat in south Bermondsey coming in January 2011.
Palace striker Jermaine Easter, on loan at Millwall, won't be able to face his parent club.
However, captain and centre-back Danny Shittu received a second yellow card after the final whistle last Tuesday for protesting too much over Blackburn's winning penalty, so he looks set to miss the game and that will be a big boost for Palace.
Parr is confident his team-mates can get the job done going into the final games and says it's important to show more "character".
"I think at this time of the year it doesn't matter who you play, they're going to be tough games anyway at Blackburn and Millwall," he said.
"We've just got to keep going from what we did last Saturday. We showed a lot of character and did a lot better because it was difficult especially without scoring.
"Now we have something to build on and I think we'll have three good games to end on before the play-offs."
