Arsenal manager Mikel Arteta must assess two integral players ahead of Sunday's Premier League meeting with Manchester United at Old Trafford.
The Gunners are already without Thomas Partey, Mohamed Elneny and Reiss Nelson, and the duo of Aaron Ramsdale and Martin Odegaard both sustained issues in the midweek win over Aston Villa.
Ramsdale managed to complete the full 90 despite clutching his thigh, while Odegaard was the victim of a heavy challenge from John McGinn and will need his ankle injury closely looked at.
Matt Turner is on standby if Ramsdale does not make the cut, but the England international will be determined to feature, with William Saliba and Gabriel Magalhaes protecting him.
Oleksandr Zinchenko is yet to return to team training following a knee injury, which means another start for Kieran Tierney at left-back, while Ben White is continuing to hold off the threat of Takehiro Tomiyasu on the right.
Albert Sambi Lokonga put in a good shift alongside Granit Xhaka in midweek and does not deserve to be dropped, while Emile Smith Rowe could act as the number 10 if Odegaard is rendered unavailable.
Bukayo Saka and Gabriel Martinelli will carry the threat out wide as ever, while Gabriel Jesus goes in search of his first Premier League goal against Man United at the 10th attempt.
Arsenal possible starting lineup: Ramsdale; White, Saliba, Gabriel, Tierney; Xhaka, Lokonga; Saka, Smith Rowe, Martinelli; Jesus
