We cannot deny because for now even though Arsenal are a very good club but for Champions League matters it is clear that they are just an ordinary club that does not have any advantage in the championship competition but that does not mean they are bad because they are still in the Champions League zone it proves that they deserve to be there but not to be champions because seeing from their golden era even Arsenal always failed and their best achievements were only finals and runners up.
The Champions League is filled with great and great clubs in all the best competitions in Europe and it is very difficult for clubs like Arsenal who do not have any experience in the finals to compete because in the end even though Arsenal are currently a great club but in fact there are clubs that are even greater than them in terms of mentality, experience and club strength.
After all, so far under Mikel Arteta's tutelage, Arsenal has focused more on its Domestic League than the Champions League. That doesn't mean they don't want trophies in this competition, but in order to remain consistent on the right track Arsenal chose to focus on their Domestic League competition. Apart from that, the competitors in the Champions League are very diverse with the depth of their respective teams. So, to stay on the right track, that's why Arteta doesn't focus too much on the UCL competition. Just imagine, just to compete with Manchester City in the Premier League, Arsenal has to use all their abilities and put in a lot of effort. If their focus is divided, then Arsenal will quickly run out of energy. however, if we look at Arsenal in the last two seasons. Arteta has built a fairly solid foundation on his team. he just needs to bring in some newcomers as the team needs, maybe after that Arsenal can become even more competitive. and it is not impossible, if Arsenal is able to win the Premier League trophy, their next target will be the UCL. although, not a very easy task.
Arteta must focus on every competition they participate in because if Arteta only focuses on the Premier League, they will definitely not be ready for a busy schedule. Apart from that, Arsenal are indeed weakened by their failure in every season because they are at the top of the Premier League standings but in the end they surrendered to Manchester City.
Arteta must think of an effective way to solve this problem where he must be able to share the same power when they play in the Champions League or domestic league because that way they can achieve the targets they want to achieve.
This season of course, Arsenal has big ambitions in the Champions League because the depth of the Arsenal squad is very strong and they only need concentration to make it happen to become champions.
Arsenal squad dept is not that strong that was why they have been surrendering to Manchester City at the last stages of the season for the past two seasons. You cannot compare Manchester City squad dept and that of Arsenal at present. Manchester City has at least two world-class players in every department but same can't be said about Arsenal. Yes Arsenal has good players but if they want to be operating in the level that Manchester City is currently they have to dive into the transfer market and add more fresh legs that are going to provide more competition to the first team squads they have already.
They shouldn't look for players that are willing to settle for the bench. They should get players that are ready to go into the first team immediately, players that are going to make the coach have headache when it come to selecting the match day squad. They need to have a player that's playing at the level of Declan rice in mid field, and same in defense and get rid of Gabriel Jesus because he is lost in the Arsenal team. Arteta need to have a team that he can rotate and keep getting good results without shivering. Only when this is done that's when Arsenal can compete effectively in all competition next season.
