Arsenal manager Arsene Wenger admits he is unsure when injured midfielder Jack Wilshere will be back in action.
The 20-year old has missed the entire season so far because of an ankle injury sustained in pre-season and although he is improving in his recovery, Wenger has not yet put a date on a possible comeback.
"It is about progress and fitness, however I can't set a date.""It is difficult to set a deadline on Jack. We go week by week with him. But his last scan was very good so we don't have worry anymore," he told the club's official website.
