The Elephants secured the first win for Africa at the 2014 World Cup, coming from behind to beat Japan 2-1 in Recife, with two goals in as many minutes from Wilfried Bony and Gervinho doing the job.
Lamouchi, however, was not about to get carried away.
“The players are very happy with the victory, but we are far from being qualified,” he said after the match. “We only won one match.
“We have another tough game ahead against the leaders of the group [Colombia]. We will have to prepare.”
Lamouchi started with Didier Drogba on the bench, with the veteran striker proving the difference when he came on.
“Having a player like Didier Drogba in the team, or among the substitutes, changes a game,” the coach added.
