Despite getting their campaign off to a winning start, Lamouchi insists that his side must not get carried away by the result.
"We didn't start the game very well by conceding through a lapse in concentration. After that, we got into a lot of good positions," he told FIFA.com.
"For us it was really important to start well this tournament. The players are very happy with the victory, but we are not yet qualified."
The Ivorians return to action on Thursday when they meet Colombia.
