The focus for Arsenal has been on the striker and midfield departments with a lack of strength in depth and the overall need for an upgrade in quality, particularly in the forward role.
However, for Arsenal, the activity has been primarily centred on outgoings. Despite the fact that four senior players, who can all play in the back four of the side, have left there is no expectation for defensive reinforcement.
Pablo Mari and Calum Chambers have left just Rob Holding, Ben White and Gabriel Magalhaes as the fit centre-back options. Takehiro Tomiyasu can play in the role but is currently out injured and his absence would leave Cedric Soares as starting right back.
