The England starlet had been out of action with an ankle injury since last summer, but he made his comeback with the Under-21s on Monday and things are looking good.
The 20-year-old played for the Gunners Under-21s on Monday as he continues to work towards reaching full fitness after the long layoff.
Arsenal was beaten at home by Chelsea 2-1 in the Premier League this weekend, but the talented young England midfielder's addition to the squad in October could be like a new signing for Arsene Wenger.
Although he is unlikely to feature immediately in the Arsenal first team, expect Wilshere to filter into matches through the month, challenging the likes of Mikel Arteta and Abou Diaby for a starting spot.
