Currently they have anticipated a shortage of players. For Gabriel, who was a bit doubtful when he had to suffer an injury, now he has been fully entrusted to Nketiah and yesterday for Partey, who was injured, now Jorginho has been brought in from Chelsea to fill that position. I think now Arsenal are still very ready and Arteta is really thinking about all the possibilities that will happen and of course that is very good.
This week they have a pretty easy game against Everton and I think it will be a win for them with the current squad.
Nketiah has filled up the boots left by Jesus really well that I see Jesus not coming back into team easily. But the case of Partey is different, Arsenal success lies on a strong and energetic defensive midfield who can bully opponents well. Jorginho doesnt seem to have that ability to fill in the gap in Partey absence. Jorginho is way too slow and isnt that physical able to go on some tackles. His side ways and backward passes might slow down Arsenal counter which is their most effective pattern of play this season. Also without Partey, Xhakas freedom in the pitch might be limited because he definitely needs to cover the defense more. Parteys absence will be felt by Arsenal and there performance might even get affected
Even though their playing styles tend to be different, in terms of experience, it is clear that Jorginho knows what to do, especially since he has been in the EPL for a long time, at least he already understands what the EPL team plays like.
I think this can actually be the difference because even at Chelsea at the moment he seems to be thrown away but still he is one who has tasted big competition and of course he is still very useful for Arsenal at this time.
