Arsenal given Laurent Koscielny boost

Arsenal manager Arsene Wenger says that Laurent Kosicelny will only be out for a "matter of days" with a calf injury.

The French defender was a doubt before the Gunners' 1-0 win at Sunderland on Saturday, having been forced off while on duty with his country during the week.

The 27-year-old then aggravated the problem during the warm-up at the Stadium of Light, but Wenger insists that the issue is not serious.

"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."

Arsenal host Blackburn Rovers in the FA Cup next weekend.
