Arsenal: Henrikh Mkhitaryan faces a late fitness test after injuring an ankle during the Europa League win over Vorskla in midweek, whilst Lucas Torreira is also a doubt with a knee knock picked up in that game. Sead Kolasinac (knee), Carl Jenkinson (ankle), Laurent Koscielny (achilles) and Ainsley Maitland-Niles (leg) all remain sidelined.
Everton: Richarlison is expected to come back into the side after suspension, whilst Yerry Mina is in line for his debut after recovering form a foot injury. However, Seamus Coleman (foot), Andre Gomes (hamstring), Phil Jagielka (knee), Michael Keane (skull) and James McCarthy (leg) as all still missing.
Arsenal boss Unai Emery:
"We've won two matches away and that's small progress, but very important for continuing to improve our confidence. I think we are finding the balance.
"Now it's very important, and our objective, to improve in the defensive moments."
Everton boss Marco Silva on his side's front-foot approach:
"It is our way. We cannot change everything because we play against a strong side. They will make us in some moments do things we don't like and create problems for us.
"But when we have the ball in our offensive transition, in our offensive organisation, we have to keep our football, our way to play, to create problems for them."
