Arsenal lost their last Premier League match against Bournemouth. And the main reason for Arsenal's defeat in this match was William Saliba's red card. After Saliba received the red because we saw Arsenal's players not performing well. Arsenal lost 2-0 in the end.
I personally also don't really understand Arteta or Arsenal's management. Because they should be aware of this, and build their squad to be even better. But in fact, until now Arsenal's squad can be said to have almost the same performance as the previous season. Maybe Arsenal's management and Arteta think that with the squad they currently have, Arsenal will definitely be able to become champions in the English league. Because maybe they see from Arsenal's records in the last three seasons which have always been almost champions in the English league. That's why Arsenal's management and Arteta think that they don't need new players anymore. In fact, if they think like that, I think they are very wrong. Because when a team has difficulty becoming champions in a football league, there must be a gap that must be fixed, even though the gap is not big. Especially in a very tight league like the Premier League, having even the smallest gap will have a big impact on a team being able to become champions.
