If he hasn't signed fuck all with Wolfsburg yet he could be in squad. I mean numbers will be light, Salah probably won't get a spot on bench, Fabregas, Costa, Mikel is still a doubt. Not the game for youth so if Schurrle can play one last game before leaving, or at least make the bench, do it. I do suspect though if he is on the bench, he'll not come on as to risk injury and medical failing
