#3 Shkodran Mustafi
Shkodran Mustafi is not the most popular player among Arsenal fans and is yet to convince them of his place in the squad. The German has failed to impress with several bouts of questionable defending since arriving from Valencia in 2016.
Despite speculation of his leaving this summer, the centre-back remained in north London and even started the opening games of the season next to new signing Sokratis Papastathopoulos.
Having cemented his place as a centre-back alongside Sokratis in the absence of Koscielny, this is the ideal opportunity for Mustafi to prove his worth. Improved ball distribution paired with his reading of the game will go a long way at proving he is suited to the game Emery wants his team to play.
