But Wenger refused to rue the failure to secure inclusion among the top seeds and is confident Arsenal can topple any of the competition's big guns.
The Frenchman said: "We finished with 13 points which was good but not good enough to win the group.
"That promises us a very interesting last-16 game. I'm not at all disappointed that we can now draw one of the big clubs.
"It's a good opportunity to prove ourselves. Two years ago we played Juventus and won.
"Last season we played PSV Eindhoven yet lost. It's a cup game.
"I'm highly confident we can beat anybody. I have great belief in my team and their ability to grow stronger."
