I would expect Arteta's project players—such as Havertz and Raya, Jorginho and possibly Vieira—to feature in this match in order to gain confidence and a chance to pad their stats, while those who are merely good rather than preferred players such as Trossard, Smith Rowe or Nelson, will feature as subs or not at all.
Imagine this horrendous Arteta Spooky Nightmare Flat Track Bully Frankenstein XI, with Rice, Saliba and Jesus rested:
Raya
Partey White Gabriel Kiwior
Jorginho
Ødegaard Vieira
Saka Havertz Martinelli
No it won't actually happen, but Hallowe'en is upon us … so what if?!
