Cazorla used to sort it out for him. Santi's a master at getting the ball under pressure and finding a way to get it forward and behind the rush. Or he was until he died. Santi compensated for all of Wenger's Crayola planning. Now we have Coquelin, Elneny and Xhaka who, as well, can also play there. And we have Ramsey who is told to play there but plays elsewhere. And we have Jack who, if he wasn't a brain donor, might be the one player who could genuinely attempt to fill the role.
