Apart from that, Arsenal's current weakness lies only in the consistency of their performance. The reason is, the biggest reason Arsenal failed to become champions in the last two seasons was because their performance always declined towards the end of the season. That's why, Arsenal has always failed in the last two seasons. So in essence, Arteta has to be aware of his team's weaknesses and has to change them so that this doesn't happen again this season. Maybe apart from training physical strength and strategy, Arteta must also be able to train the mentality of his team to make them stronger. Because mentality also has a big influence on the performance of the players. For this reason, Arteta must also be able to strengthen his players' mentality. And speaking of Mikel Merino, it is true that he also played for Newcastle one season and scored 1 goal. So with this, of course the English league is no longer something foreign to Mikel.
We have the same thought. Since Arsenal failure in the previous 2 seasons I have always said that Arsenal failure to win the EPL title was due to Arteta failure to maintain team consistency. This is indeed the biggest problem but Arteta still repeated this problem last season which should have been better because Man City last season had a tighter schedule to chase the UCL title. I had thought that maybe one way Arteta could deliver the EPL title was just by not focusing too much on chasing the UCL. And focus on rotating players in every match to maintain the players' physical and mentality so that they can maintain their performance so as not to lose points in every match.
Len01, you said it all mate. Inconsistency and weakness towards the end of the season has been the greatest problem of Arsenal and the Mikel Arteta. If Arteta does not find any way to solve this problem, I am sorry, he is going to be deprived of every trophy this season again. He does not need to have 100% squad depth before he could effectively manage his team. What he had last two seasons and last season is able to win him a trophy if he was a good manager of the team.
I remember last two seasons that I was shouting on this forum and other social medias, begging Arteta to rest Saka and other good players from playing Europa League and focus them in the English Premier League. But he didn't listen, he rather used to his strength in all the leagues, when it was time to show strength, fatigue cut up with the players.
