Arteta’s aim is to win trophy for Arsenal next season. The team’s main target is the EPL, they wants to show their quality to win the Premier League ahead of Manchester City because they have gone far; the team is improving massively and yo be a runner up in two consecutive seasons is not easy, they lost the Premier League title in their last match of the season which shows that they can win it next season.
If Arteta can get a better chance to go far in the Champions League, they will do so because Arsenal is in need of all these trophies including the Champions League and any other Cup they will be playing next season.
Arsenal must be ready with all the targets they are aiming for next season, both UCL and EPL, of course they must focus as best as possible. Last season failure in the race for the EPL trophy was very painful because Arsenal was only 2 points behind Manchester City, so last season's failure should be a valuable lesson for the Arsenal squad this season. Arsenal overall strength is quite strong and they continue to show good concentration as they have done in previous seasons.
This season, Arsenal of course wants to win a prestigious trophy because they have been fasting for a title for too long. So I'm sure Arteta will make an effort to overhaul the team in every weak spot in the transfer market this time. Of course fans will hope that Arsenal can go further in the Champions League this season because in the previous season they were eliminated in the quarter-finals.
