i don't think arsenal played that well particularly. They lost the ball a lot but worked hard. Everyone and even last year we beat Arsenal by pressuring them. 3 at the back already means you are 1 man down in pressing. Starting Fab and not having Baka meant there was nothing in midfield. Likewise the one thing Arsenal do not do well is defend transitions. We haven't really done that well at all but i guess there is less to blame Conte for as you can't expect the team to be 100% perfect everytime and you do expect the players having to perform (pedro missed a sitter near the beginning).
Against City we might a well have given up. You are never going to out play Man City with their technical ability (they will always hold onto the ball) especially when we have Cahill, Kante, Bakayoko, Dave and Alonso (not seen enough of christensen or rudiger) in that back 5 as they are not THAT comfortable with the ball when they are pressure (passing wise, baka can still dribble it) and will more often that not play the long ball in moratas general direction (not the wrong thing to do as they aren't that comfortable on the ball).
The only other way we were going to nick a win was on the counter then (which we did brilliantly last year). Hazard who can dribble but needs the ball first and runners beyond him dragging players away and running in behind (pedro/Morata/moses/alonso depending how many they have back), you need multiple runners really.
To put Alonso one side who every fast/athletic defender has him on toast (Walker, Bellerin etc, Alonso still has his uses and we don't have that outstanding LB and tbh he's still good enough but just don't expect him to be his outstanding self against the middling clubs) and then to put Dave on the other side who lets face it, is a brilliant RB but is not good enough in attack at WB against even the poorer teams in the league (he just doesn't dribble past or even run beyond the fullback enough/have that first touch that takes him away).
Thats both wings nullified then which is half of our counter attacking game where we flood forward. Allied to Morata going off and sticking Willian and our only other forward as Hazard we could kiss our counter attacks goodbye since neither of them like to make runs beyond the last defender/drag players away.
I just felt it was very flawed and cowardly. If theres 1 weakness in Citys game its their defence and we didn't have a proper go at it
