Arsenal are now focusing on the Premier League after winning 5 points from Manchester City, Arsenal chances are very open to maintain their position until the end of the season. Arteta can rotate when his team has the upper hand against weak teams, he can withdraw the main players to give him more hours of rest and keep his condition fit so that he is better prepared when playing in big matches.
Now there is no other choice, Arsenal must focus on the Premier League and Europa League. Those are two competitions they are still likely to win this season, but I don't expect Arsenal's march to the title to be easy.
Winning the title is not going to be easy for Arsenal. Several teams are fighting for the title in the Europa League. On the other hand, Arsenal is in a good position in the Premier League. They have continued to perform consistently for a long time. However, the performance of their main rival Manchester City in the Premier League is quite good. Arsenal will lose the top spot in the table if the Arsenal team drops points in a series of matches. If Arsenal wants to be champions then Arsenal must perform consistently well. And every match is very important for Arsenal.
