Need to fix up the system, cannot build up from the back. Dias looks clueless and definitely not his forte to cut lines and find that ball, Laporte should take more responsibility.
Also in defence it's very easy for Arsenal to play it to Martinelli in space as there is no one (back 3 in attack) and he can run at Dias easily. Aké is also struggling against Saka.
Think first time in many years we've been outplayed by Arsenal in every department. To the point our best chances have come on two occasions through set pieces.
