Not actually American. Unless Di Marzio says so.
Arsenal: Chambers, Tierney, Soares out; Saka, Kolasinac & Nelson back in full training; Mari could make his debut according to Arteta
Newcastle: Krafth, Manquillo, Joelinton, Shelvey, Muto, Gayle, Carroll, Colback, Dummett, Willems out; Almiron being assessed
I think Arteta will give Nelson the nod over Pepe, and persist with Lacazette up front.
