I couldn't wait to debate about how much we should or shouldn't care about this competition any longer, so here it is!
Fortunately we have what should be a relatively routine home game vs Brighton at the weekend, but still, I'd rest everyone we can. Chambers, Welbeck and Coq are out and Iwobi seemed to be missing yesterday so we're seriously struggling to field a 2nd string side. With that in mind I'd go 4-3-3 personally:
------------------ Ooooospinaaaa
AMN ----- Holding ------ Mertesacker --- Dasilva
-------- Jack ------- Elneny ----- Willock
Walcott ------------ Giroud ---------------- Nelson
Wenger though will probably stick with 3 at the back and either shove square pegs in round holes or play some senior players.
