The pair laid on assists for one another in the Gunners' 3-0 victory over Aston Villa on away turf last weekend.
Ozil has faced criticism for failing to make a significant impact at the club following his £42.5m arrival from Real Madrid last year, but the German World Cup winner appeared to link up well with summer signing Welbeck.
"[Ozil] played very well and had a good understanding with Danny Welbeck," Wenger said in this morning's press conference. "It was a good partnership because they gave each other balls to score.
"It is tempting to keep Ozil in that central role but I maintain again that he will play where he is needed for the balance of the team and that can change game by game."
Tomorrow, Arsenal will host the North London derby against Tottenham Hotspur at the Emirates.
