Jack Wilshere is in contention to make his return for Arsenal against Crystal Palace on Saturday after four months out injured.
The England international has been absent since suffering an ankle injury in the Gunners' 2-1 defeat to Manchester United in November, undergoing surgery to address the problem.
The 23-year-old could make the bench for Saturday's trip to Selhurst Park but the trip across London will come too soon for Alex Oxlade-Chamberlain, while Hector Bellerin will undergo a late fitness test.
"[Hector] Bellerin will have a test today. Jack Wilshere could be back in the squad," Wenger told a press conference.
"Chamberlain is back in full training but is a bit short to be considered. Ramsey I think is 10 days away.
"He [Wilshere] is a bit ahead of schedule because he has worked hard. I cannot tell you whether Jack Wilshere will start.
"I've not picked the team definitely. It's difficult to come back immediately."
Arsenal will once again look to Santi Cazorla for inspiration as they look to close the gap on the top four this weekend.
The Spaniard has been in marvellous form this season, leading Crystal Palace manager Alan Pardew to tip him for the Premier League Player of the Year award.
The Gunners boss agreed with those sentiments, telling reporters: "Until now he has been the most consistent and since he has moved to the centre he has been voted player of the month twice."
Cazorla's exquisite form has seen rumours of a return to Spain crop up once again, but Wenger is unconcerned by such speculation.
"He extended his contract last year. I don't think there's anything to worry about, we've not been approached."
