I just see Arsenal repeating same thing they did in the premier league last season, just take a look at how Arsenal started very well this season just to reach this stage and starts losing points. Well, it's obvious that Arsenal may not really be strong enough to stand as title contenders this season so their match against Crystal palace may not be certain to whether they can defeat them regardless of the fact that they are playing in their home ground after all, they lost against Westham in Emirate stadium so it wouldn't be a surprise if Crystal palace also do the same.
I think is too early to predict Arsenal final position in the Premier League. Last season, Arsenal performed very well, even lead the league, but they finished the season to end up in second position. That's how they lost their chance to winning the Premier league title. Arsenal has stronger players than last season, yet they are still losing their matches. As Arsenal perform well from the beginning of the season, I thought that is how their performance should be throughout the season. However, Arsenal fail to maintain their position at the top. If Arteta continues to improve his team, I believe Arsenal still has a chance to move to the top.
It will be very difficult for Arsenal to get back to the first position in the standings. I have noticed this with Arsenal since last season, when they were very good, but at the end they didn’t perform well when the season was about to end. However, as of this season, seriously, I don’t think Arsenal's performance will decline to this extent. They are currently, because how can a team topping the standings at the start of the season and coming back to the top 4, which is a very bad result for them. I also thought they would manage to be the favourites this season due to the way they started the season, but in the end, they failed to do that. However, I think what happened to Arsenal last season will still happen this season they won’t top the standings again.
