Winning the UEFA Champions League trophy will be a big deal and a difficult task for Arsenal to achieve because Arsenal always fails to make use of the opportunity they have to win a trophy. Even though Arsenal plays against weak teams in the UEFA Champions League competition, Arsenal will still find it difficult to win the UEFA Champions League trophy. I think Arsenal should focus more on winning the Premier League title, which is a little easier for them to win than the UEFA Champions League trophy.
Does Arsenal have the ability to dominate the Champions League ? They have failed to dominate the Premier league in the last 2/3 seasons. Even though they have the opportunity to occupy the top spot of the table, Arsenal has not been able to take advantage of the opportunity. This is definitely Arsenal's failure.
Arsenal's main squad is strong. However Arsenal's performance becomes unstable when any player in their squad faces injury . And this is a problem they have not been able to solve for the last 3 years. If Arsenal had strengthened the bench team . They could have added talented replacement players to the squad, then arsenal's performance would have been more stable.
Arsenal should focus more on the Premierleague. Secure the Premier League title and then try to win the Champions League title. If Arsenal tries to win both the Champions League and the Premier League titles at the same time , the team will not be able to do well in either one.
