Red Star sat back after the restart and Arsenal had two claims for a penalty go unawarded, the first after slight contact between Savic and Wilshere and the second when the defender inadvertently handled the ball.
The Arsenal boss has used the Europa League, along with the Carabao Cup, to give game time to a number of squad players who have rarely appeared in the Premier League.
"We're not delighted with a point but we'll take it", he told BT Sport.
For a side growing in confidence after four straight wins in all competitions, another victory should not be too much to ask, even if Wenger will again rotate his squad with one eye on Sunday's Premier League clash with Manchester City. I will continue (rotating) at the moment. So overall it's good if I can combine both (domestic and European football). If you can't win the game, don't lose it. "They played very well tonight, at a high pace and they were always unsafe on the breaks".
Wenger added: "He needs these kinds of games to come back to his best level and what Jack needs is to be injury-free for a long period until the end of the season and get games like that".
With impressive form in this competition not enough to earn Jack Wilshere an England call-up, his frustrations were deepened when Damien Le Tallec's goal-line clearance denied him a first club goal since May 2015. Petr Cech will probably get a start, though, as David Ospina's still injured, but otherwise expect the same mix of experience and youth we've seen throughout the tournament so far.
Jack Wilshere grew into the game against Red Star after a notably quiet first half and only an acrobatic intervention from Damien Le Tallec prevented him from notching the victor after the break.
"We want as well to play, have the ball and create unsafe situations".
