Some people are not blaming Arsenal only because of their defeat to Liverpool, they understand that Arsenal behaves this way every season and finishes second. I do not believe Liverpool has a better squad than Arsenal since both teams bought players during the transfer window, Liverpool only spent more money than Arsenal due to the expensive players they signed. Both teams did not perform well enough during the match, there was less pressure and few goals scored than I expected.
However, if you think that Liverpool has a stronger squad than Arsenal this season, which could be the reason why they lost the game, do you remember that Liverpool made no signings last season, when Arne Slot took over the league table in his first season in charge? If Arsenal finishes another season without a trophy, I will not be surprised because this is not the first time their fans have expected so much from them without winning a single trophy.
The fans are never happy, we know that, especially if the team is doing very badly, they complain a lot and start looking for a scapegoat, it's always like that
The only thing Arsenal can do is to get down to work and improve and try not to make any mistakes in the other games.
