The fans will really be happy for the recent progress of arsenal by reaching the champions league final and for winning the premier league trophy and also for the fact that they are among the Europe's elite shows they have really improved under Arteta and they will be willing to compete more this coming season. However, this is a starting point for arsenal rather than the final destination for the teamz they must continue to maintain this level of performance to win major trophies. Winning at the highest level especially in the champions league is one thing they will need to work on right now. What arsenal will be fighting for will be the champions league trophy since they are yet to life the trophy for now and lifting the trophy will be a huge achievement for the team what they need now is consistency, proper fitness and preparations for the next season because the expectations will be very high now.
That's true, they really need to work on that very aspect of winning the champions league this season even though it's not an easy task. That along will speak more about them and set them above this level. However, if they can actually achieve bringing the champions league troop home, it will enhance back their confidence and their various fans across the world will once again count and believe in them. And again, the best advise I will suggest is for them to strengthen their attack, they should emphasize more on wining matches by this they will literally be on a better chance of lifting the trophy.
I agree that Arsenal made a big step forward this past season and finally, after 20 years, became champions of England and played in the Champions League final again after 2006.
However, it will be very difficult to repeat those results this season.
Last season was a transitional season for Manchester City and Liverpool and they were not at the highest level, which made Arsenal's path to the title easier.
Also, it must be honestly admitted that Arsenal was lucky in the Champions League draw and avoided the toughest opponents before the final, such as PSG, Bayern and Real.
I think it will be very difficult for Arsenal to repeat those results this season and that the top European clubs, such as PSG, Bayern and Real, are still a level above them, financially and organizationally.
