Arsenal's elimination from the Champions League last season was not because they focused on Premier League games, Arsenal did not concentrate on the Premier League, which is why they used all of their key players to compete in the Champions League, it was just that they lacked the strength to compete in the Champions League, and Arteta seemed to give up. If you remember the game against Bayern Munich in the quarter-finals, you'll agree that Arsenal isn't good enough to compete in the Champions League. Arsenal has not won a trophy in a long time, and the last two seasons gave a perfect opportunity for them to do so. They don't need to fight like Manchester City, who won the treble the last two seasons, we believe that City has a good record of winning titles, but Arteta's next goal should be at least winning the Premier League, which other managers were unable to accomplish for the club for many years.
I also think that if Arsenal only focused on the Premier League, they would have a bigger chance to win the EPL because it would not only save their energy but they would also have many moments to keep Man City away, whose concentration is split into 2 targets. Unfortunately, Arsenal pushed their luck by striving for both tournaments. Giving up one opportunity is not a decision that is taken easily but, if Arteta doesn't dare to take that risk, then Arsenal will remain under the shadow of Man City.
