In addition to poor consistency, Arsenal are too ambitious to be excited in all competitions hoping to win titles in several competitions. While the Arsenal coach ignores how the condition of all Arsenal players who are not ready to pursue titles in all competitions. So Arsenal will continue to fail because the physical players become weaker before important matches. If Arsenal were able to prioritize one of the competitions such as the EPL title, at least have the experience of how to maintain a position at the top of the table. After successfully maintaining consistency at the top of the EPL table, Arsenal can pursue titles in other competitions. But all of this actually depends on how the Arsenal coach's strategy is.
That means Arsenal does not make a priority scale and maybe chasing Triber in one season is not an easy job if it does not have the depth of the squad. Realistically, I agree that Arteta needs to make a target and it must start from the English League first because if you pursue everything in one season it is not easy to do and in the end they always fail to offer the title.
Next season the competition in the Premier League will definitely be far more difficult because some other teams will definitely try to do the team overhaul to make it stronger. Now how the condition of Arsenal can make adjustments and have a clear target to get a trophy and if Arteta also fails again then I am sure this team is indeed not worthy of being a title challenger.
