Nice coach Lucien Favre is delighted with Mario Balotelli's impact.
The Italy striker has scored four goals in two games.
And they have helped fire Nice to the top of the table, where they sit a point ahead of Paris Saint-Germain after six games.
“I speak to Mario every day, he seems very receptive," Favre told reporters. “He has finally returned to being a happy and proud player."
Nice's next match is away to Nancy on Sunday.
