Losing six points in two consecutive matches is a big loss for Manchester City, the defeat against Arsenal may be acceptable because Arsenal is one of the teams capable of providing competition for Manchester City this season. The absence of key players could have an impact on Manchester City performance, Pep Guardiola must devise a strategy to cover his team's weaknesses in the last two matches. Returning to winning ways is the only way Manchester City can maintain competition with Arsenal. The domestic league journey has not yet reached the middle of the season, there are still many matches to be played and anything can still happen during that duration.
No matter how strong Manchester City is, it certainly has its weaknesses, and if these weaknesses are left open, Arsenal certainly won't want to waste this opportunity. Pep Guardiola may have been careless in thinking they could beat Arsenal like last season. Meanwhile, the fact is that Arteta has an ambitious soul who doesn't want past mistakes to repeat themselves. Try your best to improve the team and learn Manchester City's weaknesses.
6 points have passed and will be an important note while Kevin De Bruyne is still recovering from injury. The Premier League is very tight so you feel safe just because you are the defending champion doesn't mean it will continue. Other clubs are also developing quite rapidly, especially Arsenal, which incidentally has talented players who will make it easier for Arteta to design strategies.
