Mikael Silvestre and Amaury Bischoff made their first appearances for Arsenal in Monday's reserves clash with Stoke.
Silvestre, who joined the club from Manchester United in August, has yet to feature for Arsene Wenger's first-team due to injury.
However, Silvestre has put himself in contention for Arsenal's next game against Everton on 18th October by coming through the full 90 minutes against Stoke.
Bischoff, who left Werder Bremen to join Arsenal in July, has been struggling with a groin injury, but he played for 57 minutes on Monday.
The news will be a boost for Wenger as he looks to get his side back to winning ways in the Premier League when Everton travel to the Emirates.
