The Eagles boss has vowed not to give up on Palace's chances of making the top six despite seeing the side drop more vital points in the home draw with fellow promotion-chasers Ipswich on Tuesday night.
"I am certainly not giving up on the play-offs, even though it will obviously be very difficult now. We are nine points back but if we get a run of results together then who knows what can happen?" he said.
"One thing is for sure, a lot of teams will take points off each other from now until the end of the season and there will be a lot of upsets."
