The prolific striker has been heavily linked with a switch to the Emirates in recent weeks and has suffered a major falling-out with the Dortmund hierarchy as he attempts to push through the transfer.
The 28-year-old has been dropped from the first-team squad several times this season for "disciplinary reasons", which have allegedly included being late for training and skipping team meetings.
Dortmund are now keen to offload the player this month and are believed to be in advanced negotiations with Arsenal over a deal that could be worth as much as £60m.
Pressed for the latest developments at his weekly press conference today, Wenger told reporters: "I have nothing to add on that. This kind of thing is better when it's secret and when you don't comment before announcing it when it's over the line."
Asked if Aubameyang would "fit in" at the Emirates, Wenger added: "Yes, because character can be a very positive note and negative, but overall you look at the achievement of a player over his career and when it's been positive the character has been used in a positive way."
Aubameyang has 98 goals to his name in 143 Bundesliga appearances during his four-and-a-half years at Dortmund.
