Arsenal are not in a province problem yet, they can handle themselves because they're competitive for the league title. Arsenal headcoach, Mikel Arteta is doing great without limits and he's one of the best coach currently in England this season. I've closely watching how Arsenal improvement this season, really a tough long run and tight spot for the club. Arsenal have tried their best to make good running winnings but it will always end up not corresponding with the current situation.
In my opinion, Arsenal's current performance reflects Arsenal's performance last season, they played well and sometimes were at the top of the standings but Arsenal were unable to maintain their position for a long period of time, and actually made mistakes towards the end and allowed Manchester City to lead the league again and win the title. Because of this, many people doubt Arsenal even though currently Arsenal is at the top of the standings because the competition is still not over.
I also know that Arsenal is currently experiencing good improvement, matching last season's performance and this season is a little unfair for him. But actually by equalizing this, it could be a challenge for Arsenal to prove their abilities and do their best and be better than last season so that these doubts can be dispelled voices doubting Arsenal this season, I myself have high hopes for Arsenal but if it fails I will no longer be surprised.
Arsenal still have many matches to play and of the many matches, there are some that Arsenal will face quite serious problems because they will face other strong rivals who will make it difficult for them to win the Premier League title.
