William Saliba's injury is "the second one in a really similar area. So we didn't know exactly the time frames of that," Mikel Arteta said, on why Arsenal signed Ezri Konsa. Asked if Saliba walks back in over Konsa once fit, he wouldn't commit: "great problem to have."
Arsenal's William Saliba (back) has another scan to come; Mikel Arteta said "every sign so far has been very, very positive". Christos Tzolis hoped back "in a few weeks", Piero Hincapié needs "another week or 2". Martín Zubimendi faces a late test for the league game at Forest.
