"It's going to be a difficult task, but not impossible. If we get a chance we have to take it," Allardyce told reporters on Friday. "It's a game for us to try to get a point in - or three."
Allardyce also said that Palace would need to further improve their current form as they still have to face each of the current top six teams with 10 games left.
"Ours is the most difficult run-in in the bottom 7, looking at it on paper. We've got to be better than we've been in the last three," the former England manager added.
Crystal Palace's 2-1 over Chelsea in 2015 is their only one win at Stamford Bridge in the past 20 years.
