The Gunners have made their move for the highly-rated 17-year-old forward, who is also being tracked by Newcastle and Stoke.
It is understood that Niang will link up with Arsenal this week but new Caen coach Patrice Garande does not believe he should be looking to leave at this point.
"What I say in relation to him is simple, he has talent - yes, does he have the potential to make a career - yes," he said.
"But is he doing the right thing for this at the moment - no."
Asked if he would be using him next season, Garande replied: "If he is here I will count on him, he leaves tomorrow we won't."
Niang scored twice in 14 starts for Caen in Ligue 1 last season.
