As right now few players are in media for their transfer into Arsenal surely look like management is ready to spend big amount which will bring quality players and results will be surely also good.
I have also heard that Arteta will bring in some new players if the opportunity arises, but I don't know because you never know who they will meet in this transfer window. There is potential to see a new striker as a potential replacement for the injured Jesus, but let's see how much the rumors will turn out to be true.
Before Gabriel Jesus was declared injured, Arsenal were one of the strong candidates in this competition. however, since Gabriel Jesus has been ruled out due to injury. Arsenal's chance to win two trophies at once seems difficult to realize. the reason is, we don't know how much influence Jesus' absence has on the team's overall performance. although, on the other hand Arteta has many options regarding a potential replacement. and as we know, currently the most realistic to play as the main striker is Eddie Nketiah. plus, there is Gabriel Martinelli who can be pulled as a center forward. but in fact, we don't know for sure whether these two players can be a solution to the Gunners' needs.
As for the several names that will be brought to the Emirates Stadium, in January. similarly, they also require adjustment, chemistry, and bonding between the players. I'm sure this situation is unpleasant for Arteta. even so, I hope Arteta is able to answer the team's needs and continue to bring his squad to perform consistently after all leagues are rolled back.
