Yes Arsenal have won only local championships in team history. Maybe they could have achieved the Champions League title in their past when they had great players such as Thierry Henry. Now they are building their future with young and talented players. Arteta has done a really good work with this squad so far. There was a big improvement last season. But it is still doubtful if they can show the same performance in the Champions League as well. It has been a while since they joined this tournament the last time.
But if we see consistency in the Champions League as well they can at least be good enough to get past group stage. It is up to having a good draw as well of course.
Arteta has done so much work for arsenal by bringing young players for next season and this will definitely improve arsenal without no doubt but I'm not so sure if arsenal will have that energy to win the Champions league. Arsenal failed to win Premier league last season and the main target for arsenal next season should be winning Premier league, it won't be easy for arsenal to be fighting for Premier league and champions league because the team is just coming up, it will be better they go after one trophy.
Having Emirate cup is another confirmination that Arsenal is ready to battle in the Champions League but at what expenses did that cost Arsenal. Today, I observed that Gabriel jesus was absent even on the bench, till I later realised that he has a knee injury from their last match with Barcelona, it is not a good signed from Gabriel but Nketiah did a good justice by equalizing the goal for Arsenal which made them draw until the last minute of the match before they proceeded to penalty and Arsenal as become 7th time Emirate cup winners.
It will exhusting for Arteta for the continue injury of Jesus, had it been Nketiah was not on ground, it will be a heavy task for Arsenal to play well just that I think its when Gabriel Jesus is not around Arteta use Nketiah and he never failed to disappoint. If Jesus career is going to continues in this dimension, the earliar they sell him for any club that want him so they can invest the money on another striker, they have now qualified for the Champions league which means there is more work to be done unlike when they use to play only the Premier league.
