However, the lack of organisation at the back coupled with far too many errors on display on Friday night will worry the Arsenal boss, as well as the club's world-weary fans.
Ibrahimovic's made the move from Ligue 1 to the English top flight last season, and managed to score 17 goals in 28 league appearances for the Red Devils, a return Wenger feels his new striker should try and match.
Unfortunately, Arsenal will be missing star player Alexis Sanchez to injury and Leicester will be missing summer signing Iborra to a groin injury during training for the upcoming season.
But his first goal of the new campaign could prove one of his most important already as Arsenal clawed their way back twice to kick-start their season. We had some avoidable goals which we conceded and overall we have to work on that. What the game was, though, is a reminder that beyond the incessant transfer rumours and long, moody shots of Arsene Wenger staring into nothingness awaits the adrenaline rush that only a good game of football can give. "We have to be positive as it's the first game".
"I love the man and the player, he doesn't want to leave and I'm happy he wants to stay".
