The 21-year-old returned to first-team action in late October after a 14-month injury layoff and has been in impressive form since then.
"Maybe [I won't rest him] in this period, but at some stage I will do it," Wenger told Arsenal's official website. "At the moment I don't think he is overloaded because he just came back very recently, and you get the feeling that he gets stronger.
"We have a good approach taking the physical analysis and statistical analysis between what the player feels and what the medical department thinks, and you have to come to a conclusion on that.
"At the moment, all these three are positives so I don't think at the moment I will rest him immediately. But it will happen."
Arsenal will host Swansea City in the FA Cup third-round replay at the Emirates Stadium on Wednesday.
