Crystal Palace vs Arsenal: What are we thinking?

A minimum of a draw is required to get back 4th, but a win will surely keep our momentum going. What are we thinking about this match? Sellhurst Park is a tough place to go to and we've struggled there recently. You guys think we can get the win? When I look at it as realistically as possible, a draw seems most likely. Still puts us in the driving seat for 4th, but no ideal.
