Arsenal youngster Alex Oxlade-Chamberlain is in danger of missing Saturday's visit of Blackburn with a knee problem.
Oxlade-Chamberlain has been one of the few bright points recently for a Gunners side that has not won in four league games.
Arsenal currently trail fourth-placed Chelsea by five points in the hunt for a Champions League spot and know victory is a must against Blackburn.
Arsene Wenger recently attracted criticism for his decision to withdraw Oxlade-Chamberlain in the 2-1 defeat to Manchester United, a situation magnified by the role of replacement Andrei Arshavin in United's winning goal.
This Saturday, Wenger may not have the youngster at his disposal due to a minor knee issue, and the Frenchman also admits the game may come too soon for Kieran Gibbs, back in training after two bouts of surgery.
"We have a little problem with Oxlade-Chamberlain that we have to check today (Friday) because his knee jarred a little bit and we will see how he has recovered from it," Wenger said. "All of the other players look alright.
"Gibbs is nearly ready but what he lacks is a little bit is confidence. He has not played since the beginning of October. He had two surgeries so I will have a little chat with him. He maybe needs a game with the reserves, I do not know yet."
Wenger has also confessed that he may be tempted to rest some of his players following the 0-0 draw at Bolton, which will instantly spark fears that top goalscorer Robin van Persie may be set for more bench duty.
"We gave a lot on Sunday against Villa and gave a lot against Bolton on Wednesday. I am thinking about it at the moment, yes," Wenger commented.
