Yes, you are right, it is not easy for every club to achieve their expected targets even though they only focus on one competition, like Tottenham last season where they only focused on the Premier League because they did not play in the Champions League, in fact they still had difficulty winning the Premier League title. Even though at the start of the season he seemed to consistently win, as did Arsenal, he still had to perform as well as possible in the Champions League because this is a prestigious competition even though his target was to win the Premier League title.
Talking about Tottenham, I was quite surprised to see they never improve in almost every season. Their abilities stop there and they couldn't be any better. In fact, they are a team that really has the potential to make a big surprise in the Premier League.
If I compare, what they experienced is almost the same as what Borussia Dortmund has experienced in the Bundesliga for at least a decade. Even though Tottenham never lacked quality players, especially when Harry Kane was still with them. However, it is the team's performance that seems to be making them difficult like this, apart from the competition which is indeed very competitive.
I believe Arsenal can go further in the Champions League and also try as hard as possible in the Premier League, the most important thing is that Mikel Arteta can always overcome existing mistakes without having to feel pressured because Manchester City will always remain their main competitor. I have seen in the last 2 seasons actually Manchester City is not much different from Arsenal, as long as this club remains focused, then they can break Man City's dominance.
Many have high hopes for Arsenal, you also have to consider that many teams have strengthened a lot, I like the way Arsenal plays, I just hope that this season they are more consistent in their games and win more, because sometimes they explode with genius and win games that are very difficult, making it clear that they are very strong, but suddenly they lose against a team that is not doing very well in the PL, and that is already disconcerting, I think that if they correct that, they could even be fighting for 1st place, let us remember how City and Liverpool are doing, they are teams that go with everything.
Arsenal already have a strong enough foundation for them to continue next season, from season to season they always show improvement and improvement, this is a breath of fresh air for them and then they can achieve something they want. Mikel Arteta has so far been able to carry out his duties well, now it's just a matter of how he can create a squad that is more consistent.
If we reflect on their failures in 2 consecutive seasons, in fact they always have very good momentum. It's just that at the same time they slipped a little, which opened up opportunities for other teams to overtake them, and Manchester City, as their rival at that time, did not miss the opportunity that came to get back above Arsenal.
