Arsenal have won just 1 game out of their last 5 games played and things are going to look bad for Arsenal if they are not able to gain points soon to maintain as one of the top 4 teams on the table. Crystal Palace will not be an easy team to beat with Roy Hodgson leading them but I think since Arsenal will have the privilege to play this upcoming match at their home stadium, Arsenal should stand a high chance to earn 3 points from the hands of Crystal Palace at the final whistle.
Don't worry, I'm sure Arsenal will win. They've suffered lose streaks, so all the players must be motivated to win especially Crystal Palace is just a mediocre club. Crystal Palace just lost against Everton yesterday, so they should be lack of stamina.I can't deny if arsenal has a better quality on its squad but fulham was also a mediocre club. This is football, as long as palace use the parking bus and it can also steal some points from arsenal. It will make this club has less chance to get the trophy this season.
Even though Arsenal's performance is declining, but Crystal Palace is worse than Arsenal. Unfortunately the match is not worth to bet, the odds is too low and it's full of uncertainty.
Let's see that. Arteta hopes he will not repeat the same story like when arsenal was facing fulham as its opponent. You will be shocked if arsenal will continue its lose streak soon. 
Come on palace, just show arsenal the parking bus.
