You are absolutely right, for me Arsenal had a great season, they took advantage of all the teams' absences in the UCL to go up like they eliminated Madrid it was epic and I recognize it, it is a shame that they were not consistent because it would have been nice to see a great fight against Liverpool for the PL, however I agree with what you say about City, Pep was going through a very bad moment but he is a guy who overcomes things, and this season with new players he can do what he always does best which is win.
How was Arsenal's season great? Coming second again for the 3rd consecutive season isn't supposed to be great for a team that's supposed to win the title at least once in those three years that they claim they had a great season. Anything short of winning a title isn't supposed to be considered great. After eliminating Real Madrid both the team and fans all thought they've arrived and thus winning the champions league was their agenda, lol.
Is it possible for a team without a winning mentality and do not have the spirit of championship in them, win the Champions League. I love Arsenal fans because they are big dreamers and too fast to win trophies by words. Arteta needs to find a way out of this position and move higher in order for them to win the title after a long time.
Arsenal have been runners-up in the Premier League for 3 consecutive seasons, so that's not progress but a failure, even though Arteta has spent a lot of money to build the Arsenal team in the last few seasons, there have been no visible results, so I am very surprised at the optimistic attitude of Arsenal fans who continue to dream of the same thing every season.
Arsenal is a team that does not have a champion mentality, they have good performance at the beginning of the season but when they are in a fierce competition for the championship title they will falter and this has not been found a way out by Arteta in the last 3 seasons so I think now Arteta is the problem, if Arsenal management continues to trust Arteta, maybe the same thing will continue to happen again.
