Did you think Arteta learned from his mistake last season? He is still using the same strategy that he used last season. Arteta needs a striker, and Saka should be allowed to rest. As we can see, Saka is not really in form this season compared to last season, but Arteta is not giving him rest, he keeps on using Saka in all his matches. Arteta needs a perfect replacement for Saka, he should be given enough rest. Most defenders now understand Saka's playing pattern and the ways clubs are building their defense when playing against Arsenal. It’s always difficult for Saka to penetrate their opponent’s defense.
 
In most matches that Arsenal are playing, they are always dominating, but they are always finding it difficult to score goals in their matches, and most clubs are always playing defensive games; if they have any little opportunity, they do use it well. That’s why Arsenal do dominate most of their matches lately, and they do end up losing.
