Victory at Selhurst Park would take them to 59 points - 12 more than their previous best in their inaugural Premier League campaign in 2011-12 - but Monk is wary of Palace being fresh from winning 3-1 at Liverpool and carrying a real forward threat in the shape of Yannick Bolasie, Jason Puncheon, Wilfried Zaha and Glenn Murray.
"They were fantastic against Liverpool and they've got a good blend of players, especially attacking-wise," Monk said.
"Alan Pardew has done a great job since going there from Newcastle and is building a good team.
"The run they went on when he took over and to get them where they are now shows how difficult it will be for us.
"They also have a possibility of moving up another two places in the league so they're going to be scrapping for that."
