Second option: Winger in a 4-4-2
A major problem for Arsenal last season was the numbers of goals they conceded.
In light of this, the option of using a 4-4-2 system may be considered, as it provides a 4-4 block behind is the easiest way to organize a defense.
Also, after losing Aaron Ramsey to Juventus in the middle of the field, a 4-4-2 could be the best option to organize also the attack.
With this system, Pepe’s best position could be out on the left-wing.
Arsenal have brought through Alex Iwobi, who is a player with a solid defensive ability on the right side, so the left side could be the good place for Pepe to show his attacking skills.
