Arsenal this season makes things very hard for the other teams especially City. It has been quite long time since gunners were performing like that.
The victory against Liverpool with 3 goals to 2 was impressive.
They won against Liverpool and everybody knows that Liverpool is in pretty bad shape right now even Manchester United was able to dominate them so yeah there isnt anything special about this. I'd love to watch Arsenal play against some other top teams right now to convince me that they have a shot on the top spot otherwise its pretty unconvincing though
generally speaking, if they can beat all those teams that they played against so far, they're are good, I don't think they really need to beat Manchester City to prove how strong they are, they already beat Tottenham who are in the third spot with 20 points, Man City are the only one big left, but I'll say it again, it won't prove anything when they face each other, what matters the most is consistency, and they're killing it so far.
