Jack Wilshere could make his comeback on Saturday against QPR after completing another 90 minutes for Arsenal's U-21s.
The midfielder has now played two full matches in five days after completing a behind-closed-doors friendly with Chelsea last week.
Wilshere was impressive during Monday's 2-1 win over Everton's U-21s in a game that also saw Bacary Sagna and Emmanuel Frimpong continue their comebacks.
The England midfielder's return is a boost after Saturday's shock 1-0 defeat to Norwich. Arsenal have won only one of the last seven Premier League games started by Wilshere's deputy Aaron Ramsey.
But Arsenal are still missing Alex Oxlade-Chamberlain, Theo Walcott, Lukasz Fabianski and Wojciech Szczesny ahead of this week's Champions League clash with Schalke.
