Jack Wilshere could be making a comeback during Arsenal's Premier League clash against Crystal Palace on Saturday.
The 23-year-old, who has been out of action since November after sustaining an ankle injury during the Gunners' 1-2 loss to Manchester United, returned back to "normal training" ahead of Arsenal's FA Cup clash against Middlesbrough.
Although the midfielder did not feature during his side's 2-0 win against Boro, he is believed to be in contention to start at Selhurst Park on Saturday.
However, Wenger refused to reveal whether the England midfielder would be starting on Saturday.
"I cannot tell you whether Wilshere will start," Wenger said in the pre-match conference. "I've not picked the team definitely. It's difficult to come back immediately."
The Frenchman also threw some light on the progress of his other injured players including Hector Bellerin, Alex Oxlade-Chamberlain and Aaron Ramsey.
"Oxlade-Chamberlain is back in full training but is a bit short to be considered," added Wenger. "Ramsey is 10 days away."
Meanwhile, Wenger says that he is confident that Santi Cazorla will continue playing at the Emirates despite him being heavily linked with a move to Atletico Madrid.
"He extended his contract last year," the Arsenal boss added. "I don't think there's anything to worry about - we've not been approached."
Wenger admits that Cazorla is an important player for Arsenal, insisting that he has been the most "consistent player" for the Gunners this season.
Cazorla has been in impressive form this season, particularly since the turn of the year, and Wenger added: "He has been the most consistent player. Since he has moved centrally, his influence is bigger."
Elsewhere, Wenger has confirmed that Thierry Henry has started coaching Arsenal's youth players.
The 37-year-old, who recently ended his playing career at MLS side New York Red Bulls in December, is currently working as a television pundit for Sky Sports.
However, Wenger has confirmed that the former Arsenal striker has also started his coaching career.
"Thierry Henry is making his first steps as a coach," add Wenger. "It's good for our youngsters to be coached by him. He's been here once or twice."
"All our former players are welcome to come back here and get their coaching badges. We're happy to have him."
