The Gunners boss has been in charge of Arsenal for 17 years now but his current contract expires at the end of this season - leading to speculation linking him with a potential move to Paris Saint-Germain.
Ahead of Tuesday's mouth-watering Champions League clash with Borussia Dortmund at the Emirates, however, the Frenchman was giving away nothing.
He told Sky Sports: "I will make a decision halfway through the season. Deep down, I have an idea what I want to do, but give me a bit of time. What interests me above all is to always meet the expectations of our fans."
Wenger has previously put his neck on the line this season by saying how this team played this term would determine whether he stayed with the club.
His players have certainly responded, dropping points only to West Bromwich Albion since the opening-day defeat at Aston Villa. They also go into tonight's clash with last year's Champions League and Bundesliga runners-up with a perfect record in the competition, thanks to Mesut Ozil's world-beating performance in the 2-0 win over Napoli.
When questioned about feeling his age, however, Wenger shrugged off the idea.
He said: "Who is this guy who is 64? You never believe you are 64. When you are 50, you don't believe you are 50. Internally you are still young, externally you become old.
"I want to feel I can do well for this club. It's as simple as that. It's not a question of my loyalty. I can build another new team, but I haven't got 17 years, that is for sure.
"At the minute I'm looking at the short term. I will make a decision about the little bit longer term later."
Arsenal will tonight be looking to extend their unbeaten run in all competitions to 13 games.
