The Gunners head to Chelsea on Sunday to take on a team against which, last season apart, they had struggled to match in terms of strength on the ball.
Wenger's great Invincibles side never had such problems, with the likes of Tony Adams, Martin Keown, Emmanuel Petit and Patrick Vieira coming out on top in the duels, his players receiving more than their fair share of red cards since he took over in September 1996.
The French coach believes while Arsenal's new generation have taken their game to another level in terms of finesse, an added edge would not go a miss.
"Maybe we have to go back a little bit, not less technical but a bit more physical and aggressive," said Wenger, who on Friday was boosted by the confirmation Theo Walcott had finally signed a contract extension.
"I think that when [referees] see Arsenal on the sheet, they say 'oh fantastic' [to referee them].
"This side are physical players, but we have to restructure the balance of the team a little bit.
"The players have the character to do it. The [likes of] [Jack] Wilshere are technical players, but they are also physical players."
