I don't want to have any hype about Arsenal to fight for the Champions League title next season. I really appreciate with the work they did in the EPL the last time. But it is quite difficult to keep up the same level with a young team like them. Besides this is the CL we are talking about. This environment is way more different and Arsenal haven't had any experience in it for many years.
Arteta would of course prepare his players in the best way possible. But I think they would have big struggles against top experienced teams.
The Champions League format has completely changed now as well but I don't know if we would see big surprises in its first year in some stages.
Arsenal really surprised people last season in the premier league competition that made the team to embraced second position, which is a sign that the team will do better next season to break some record to make the coach and fans happy. Based on some of the tactics the young players displayed in the premier league tournament, I think they will make the champion league competition difficult for some strong teams next season to ensure they achieve the title and make the team stronger than Manchester city. Now that Arsenal management are fully ready to maintain their young talented players in this summer, I believe there will be positive results next season because they will ensure they increase the number of goals from the beginning of the tournament till the end.
