Koscielny boost for Gunners
Arsene Wenger says Laurent Koscielny's calf injury is not serious and should only keep him out for a matter of days.
However Koscielny failed a pre-match fitness test and Wenger decided not to risk him for fear of aggravating the problem further. It was a wise decision as Wenger says he will not be on the sidelines for long.
"It's a calf problem. We think it's a question of days [until he returns] because he had a positive scan," Wenger revealed. "He [came off for France] at half time [on Wednesday] and we decided to give him a trial in the warm up.
"He was not good enough. I don't think it's long-term."
The defender picked up the injury when playing for France in midweek and was given every chance to make Arsenal's clash against Sunderland at the Stadium of Light on Saturday.
