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.
Maybe Arsenal is experiencing conditions similar to last season. Even this season I think it's worse. Because last season we saw Arsenal still ranked at the top in the middle of the season. And dropped to 2nd place at the end of the season. Arteta seems to have to rebuild the squad. More thorough preparations must be made for next season. But this season there is something different, namely Arsenal will fight in the last 16 of the UCL. So Arsenal's goals may be much bigger this season. But with the current conditions, it is natural that doubts are starting to creep in among all Arsenal fans.
against Crystal Palace shouldn't be a big deal. But maybe Arsenal will find it difficult to score many goals. Arsenal will probably win but with a narrow score.
One of the major problem of Arsenal is lack of depth which has been the same problem of last season, though they did sign two players, Havertz and injured Timber of course those signings hasn't made the squad more formidable and again it's obvious the team lack a competent striker and Arteta hasn't address that problem take a look at most the matches they lost they dominated and took most of the possessions yet couldn't register or score goals, the team is the architect of their own fortune if the management is ready to win the league they should do the needful by signing top striker, with their next match against crystal palace as it's going to be a tough match because now Arsenal is unpredictable.
