The English League is a very prestigious competition, and all the teams competing of course have very good strength; therefore, all those competing must use all their strength to win. When there is a difference in points that big, they must win the next two matches to have a chance. to seize a position above him. Liverpool and Manchester City will be very difficult opponents to beat, so Arsenal will have to work well as a team to get the win.
Arsenal must immediately restore their best performance that they showed at the start of the season. They cannot continue to be in such poor performance as they are currently. The current situation had even raised doubts among everyone. In fact, usually the Arsenal vs Crystal Palace match would definitely be considered a match where there is no need to debate about who is the favourite. But now even people are starting to doubt that Arsenal will face Crystal Palace. This happened because Arsenal had lost to West Ham and Fullham.
And yes, the competition this season doesn't only involve Man City, which could be a big obstacle for Arsenal. But this season even Aston Villa and Liverpool have also joined the hunt. And behind Arsenal there is also Spurs whose quality of play has improved rapidly compared to last season. So Arteta's task is much more difficult this season.
It is left for Arteta to set a wrong formation which will make him lose again.You are right that the game between them and Crystal palace is a game that will determine if they will still compete for the tittle or not.If they should lose or draw that game,then it will be taken that they are out of theTittle race.They were in such a great form from the start of the season,but ever since WestHam won them at home,it's seemed as if it opened Arsenal's stategy and how to win them to other premier league team,they started losing games back to back,which has dropped them to fourth on the table.
