Arsenal boss Arsene Wenger has revealed that defender Hector Bellerin is back in full training and available for Saturday's away game against West Bromwich Albion.
The youngster missed the North London derby before the international break but is available for selection having recovered from injury.
Strikers Theo Walcott and Danny Welbeck are still ruled out.
"Hector [Bellerin] is back in full training," Wenger revealed.
"[Aaron] Ramsey should be available on Monday, and maybe [Alex Oxlade] Chamberlain as well.
"He [Theo Walcott] is doing well, he could be a bit ahead of schedule but still you count a few weeks more while [Tomas] Rosicky, [Jack] Wilshere and [Danny] Welbeck will be later.
"I have not talked to him [Laurent Koscielny] yet, but I will talk to him to see if he's completely recovered and focused [after what happened in Paris]."
