Arsenal are not unable to learn from their mistakes but indeed they have not been able to mentally and their performance goes up and down drastically, so they cannot be able to survive the journey.
But Arsenal have a greater chance of developing much better in the future if Arteta gets his momentum well, and can be much better than Man City, most likely he can get the EPL and maybe UCL he can also get if he develops well again in the coming season, Arteta has always been number two in the Premier League, he has always almost managed to beat Guardiola there, and is quite consistent in the English Premier League, but if in the UCl maybe because the atmosphere is different as well as the rival is much stronger making them lose a little focus and always broken.
Restoring Arsenal glory is not an easy thing for Arteta to do at this time, Arsenal once reached the peak of its glory in the 2000s and even we can see how they were able to be unbeaten in the Premier League and also reached the Champions League final before being stopped by Barcelona at that time, Arsenal journey in winning the trophy so far is certainly not as easy as turning the palm of their hand and even we can see that for more than 20 years they have had to fast Arteta has been able to take Arsenal in the right direction in the domestic league and they have been title contenders in the last two seasons, while in the Champions League reaching the quarter-finals is their biggest achievement in the last 10 years.
Currently Arsenal is on the right track with Arteta, so the management must give full support to Arteta in order to make the team even better next season, Arsenal still needs a lot of improvement in every line of their squad so the management should be able to give enough money for Arteta to get new players according to the needs of the team, So that at least Arsenal can achieve better achievements next season than this season in the Champions League.
