Among this three teams, no disrespect to arsenal but I think they are the weakest among them all due to the fact that they lack consistency to maintain the title push.
If you look at this man city team, they actually knows how to win those smaller games very well unlike the arsenal team that sometimes loose to small teams, when everyone expected them to win.
Their performance against crystal palace was very good, but the question is can they maintain such form? By putting away this smaller teams, the league is a marathon, let just watch and see how it plays out, but I see this man city team winning this one again.
Well not to doubt you Manchester city have really been tops with their performance and I'm not disputing that, the also have a good tactical approach on getting back their form even after a while of some setbacks probably due to injuries, Manchester city aswell have got a very good winning mentality which has really helped them alot.
Arsenal's inconsistency especially with how they win and loose to small team will definitely cost them the title race if they don't change to a more consistent pattern in how they handle their games. Maintaining a form without a case of injury is something they shouldn't find really difficult especially facing smaller teams, because with small teams, they get the opportunity to accumulate points enough such that when they meet with bigger teams, if the loose or draw they can still stay safe due to the accumulated points and wouldn't have to drop Below the top four bench mark.
