Arteta must feel confused about the current situation. Because in a few days they will face the London derby against Tottenham. And their opponents also cannot be taken lightly because we know that Tottenham is one of the strongest teams in the Premier League. Meanwhile, Arteta will not be able to keep Arsenal in optimal condition. Odegaard's injury is one of the things this team is most afraid of this season. this and now is happening. And apart from Odegaard, we also know that Declan Rice cannot be played due to the red card he received in the previous match against Brighton. Maybe the path that can be chosen is to reduce Trossard to midfield and play Raheem Sterling as well in this match, which will also be this player's debut at Arsenal.
I don't think this is too much, Arteta has many other options to replace the injured Martin Ødegaard although it cannot be denied that Martin Ødegaard is quite an influential player but Arteta has experienced something like this and he can solve it.
Against Tottenham is always difficult because this is a Derby match that is always presented with high tension and indeed this match will not be easy for Arsenal but personally I am still very sure Arsenal can still win the match later especially the draw in the last match against Brighton is a reference for Arsenal to be able to get back full points and advance in a positive trend for the competition for the PL title this season.
