Arsenal are very capable one and probably the next strong team after City right now. I am really hoping for Arsenal to win here but it won't be easy as City has taken a defeat in last game and they will be very careful and determined to try to win this game as well.
Let's see who wins? 
If I'm not mistaken in important matches these two teams have only lost once - Man City in the EPL to Wolves and Arsenal in the UCL to Lens.
In the English league Man City lost 1x while Arsenal drew 2x, Yeah this is not a bad result for both of them but it is as a more qualified team especially Man City they will definitely believe in visiting the Emirates stadium headquarters.
It is curious that the odds are not much different because Arsenal can still be favored at home.
