Arsenal lack second tier players on par with the first squad, I'm sure Arteta has figured that out. and that's why, the Gunners will find it difficult to play their next matches in the premier league. several players suffered injuries, as a result Arsenal lost against Manchester United at that time.
I do not doubt the greatness of the squad made by Arteta with his young squad. however, in order to continue to play optimally Arteta requires several new players. maybe in the next transfer window, Arteta will bring some players to the Emirates Stadium.
At the moment Arteta's target is clear, only to finish in the top four of the Premier League. and if Arteta can lead the Gunners squad to a title win this season, I think that would be a great achievement.
Arsenal's attractive appearance in every game will be a reason I have the same hope as you, which is to see Arsenal lift the trophy for the 2021/2022 season because the English Premier League trophy has not been brought back to North London for a very long time.
On the other hand, I still doubt that the team based at the Emirates Stadium can achieve it. My first reason is because Arteta's squad depth is not balanced between the main squad and the second squad.
Second, their habit towards the end of the competition too often loses points.
This season there is an opportunity for Arsenal to realize their hopes of lifting the trophy because Chelsea, Liverpool and Manchester United are still looking for the best formula to shape their playing pattern.
