That could be a long way off, though, as Cazorla has not featured since October 2016 due to an Achilles problem that has seen him have no less than 10 operations.
Wenger is a big fan of the 33-year-old and has dangled the carrot of a new deal at the club if he can prove his fitness.
"That depends on his medical availability at the top level," Wenger told Standard Sport. "We have to assess that until the end of the season - if Santi is fit and available to play then yes. Of course, we have to see that.
"That is why I tell you it is a complicated situation because first of all we love him, second of all he is a great football player, but the third situation is that you need to be healthy today to play at the intensity level that is needed in the Premier League. So we have to see if he can absorb that or not.
"I am not informed enough about his medical situation. I sent him a message two weeks ago and wished him well and am hoping to see him soon. He has not come back yet because he has just had surgery.
"The medical people know much better than I do whether he will play again in 2018 before the end of the season. On that front before the end of the season will be hard for him."
