To be honest, at the start of the season I didn't think Arsenal were very strong. Because there were fewer star players in Arsenal's squad than Liverpool or City. However, Arteta has proved his mettle. With the help of Arteta, Arsenal performed very well this season and continued to fight for the title until the last match of the season. Arteta will surely strengthen his squad next season, and continue to fight for the title.
Arsenal need some young players in their squad. Arsenal have no viable replacements. So when a player faces an injury, Arsenal's performance slows down a bit. So Arteta will definitely need to add some talented players to his squad this season.
Of course Arteta doesn't want to fail for the third time in a row in the competition for the EPL title with Manchester City, his failure this season was because Arsenal failed to get full points at the Emirates stadium when facing Aston Villa. The mistakes made by the team will be anticipated next season by adding to the team's strength, the arrival of new players with quality will have a positive impact on Arsenal. Arsenal young players are starting to improve in performance, Arteta needs to hone them so they have a winning mentality so they are better prepared for the title race.
Overall, Arteta has succeeded in maintaining Arsenal's performance in the last two years, they have succeeded in forcing Manchester City to always maintain their performance until the last game. Arsenal will try to do their best in the EPL and UCL, Arteta experience in handling team in big matches will make Arsenal a team to be reckoned with in the UCL.
