Arsenal have injury doubts over both Bukayo Saka and Emile Smith Rowe ahead of Saturday's Premier League clash with Liverpool.
Saka pulled out of England duty last week due to a niggling hamstring issue while Smith Rowe suffered a hip injury while away with England Under-21s.
The rest of Mikel Arteta's squad are fit and available with Martin Odegaard's ankle injury suffered with Norway not a risk to him missing the game.
Liverpool forward Roberto Firmino returns to the squad after a knee injury.
The Brazil international has missed the Reds' last three matches but trained fully this week and is back in contention.
Striker Divock Origi remains absent with a muscle problem and there is still no timescale on a return for captain Jordan Henderson after his groin operation in February.
Arsenal provisional squad: Leno, Ryan, Bellerin, Chambers, Gabriel, Luiz, Mari, Cedric, Ceballos, Elneny, Partey, Xhaka, Saka, Odegaard, Smith Rowe, Willian, Aubameyang, Lacazette, Nketiah, Martinelli, Balogun.
Liverpool provisional squad: Alisson, Adrian, Alexander-Arnold, Kabak, Phillips, Robertson, Tsimikas, R Williams, N Williams, Fabinho, Wijnaldum, Thiago, Milner, Jones, Keita, Oxlade-Chamberlain, Shaqiri, Salah, Jota, Mane, Firmino.
