Alan Pardew's men haven't won in the Premier League since December.
Norwich City boss Alex Neil believes that Crystal Palace should now be considered as participants in the relegation scrap due to the similarities they share with the Canaries side that were relegated nearly two years ago, Sky Sports reports.
Alan Pardew's men are currently enduring a rotten run of form, with Saturday's defeat to Leicester City meaning that they have still not won in the Premier League since December, in a run which now stretches 13 games.
And although the Eagles are seven points clear of the bottom three, Neil suggested that Norwich's relegation from the top flight proves that Palace should not consider themselves safe just yet.
"I took that one from where Norwich were two years ago. Five points above the relegation zone with seven games to play, sometimes you can feel as if it's going swimmingly and suddenly find yourself in trouble," he told Sky Sports.
"Trying to reverse that around is extremely difficult. Palace haven't won in  games now. They'll be concerned about that and we've got them to play. The more we drag in the better."
Like Palace this season, Norwich headed into the final part of the campaign seven points clear of the drop zone. However, they had played a game more than Pardew's men have played this time around, which could prove crucial to their hopes of avoiding going the same way that the East Anglia side did.
As Neil alluded to however, their biggest problem will undoubtedly be ending their dreadful run. Norwich ended their relegation season with six defeats and no wins from their last seven games, and with Palace struggling for any league form - which is especially bizarre given their tremendous run to the FA Cup semi-final - they may be concerned that they may be heading a similar way, especially as they have four of the top seven still to play.
And with the Canaries being their second opponents following the international break, Pardew will know that ending their poor run quickly will be vital to their survival hopes.
