Petr Cech is struggling to be fit for Saturday’s crunch north London derby against Tottenham.
The Arsenal goalkeeper limped off during the weekend win over Everton with a calf injury.
The shot-stopper was assessed by Gunners staff on Monday and Arsene Wenger will give his No 1 every chance to prove his fitness.
But it looked unlikely the keeper would be available for the trip to Spurs meaning Wenger will have to call upon understudy David Ospina, who has not made a single Premier League start this season.
