Arsenal manager Arsene Wenger has confirmed that Laurent Koscielny has a chance of featuring in this Sunday's North London derby, but Hector Bellerin has been ruled out.
Koscielny was not part of the defence that suffered a 5-1 battering at the hands of Bayern Munich in the Champions League on Wednesday due to a hip injury.
Bellerin had a "small chance" of playing this weekend, but Wenger has now confirmed that the full-back will miss the game as he continues to nurse a groin problem.
In a press conference this morning, Wenger told reporters: "We might have Laurent Koscielny back but Hector Bellerin won't be available."
Arsenal are currently second in the Premier League table, on the same points as leaders Manchester City.
