Attack their left-side
Without wanting to sound too harsh, Nacho Monreal is Arsenal’s weak point and must be got at.
Indeed, their left flanks is their weakest side and so Sadio Mane should have the chance to redeem himself after the Leicester game. Joined by Nathaniel Clyne, if the rapid two can take the Spaniard on they should be able to create plenty of chances and Mane should be amongst the goals.
