Arsenal could be without Petr Cech for Saturday's Premier League north London derby against Tottenham at Wembley.
The experienced goalkeeper was forced off in the win over Everton with a calf problem and has not trained since as David Ospina prepares to deputise.
Nacho Monreal also came off in that 5-1 victory due to illness but should be available to retain his place while Danny Welbeck (hip) is back in contention. Santi Cazorla (Achilles) remains a long-term absentee.
Tottenham's January signing Lucas Moura could make the squad after working on his fitness this week while Toby Alderweireld is in line to start after playing 90 minutes against Newport on Wednesday.
Harry Winks, Serge Aurier and Danny Rose all returned in the FA Cup fourth round in midweek and are also in contention.
