M'Baye Niang says he's change his lifestyle to prove himself at AC Milan.

The striker hit the headlines when he was kicked out of the France Under-21 team when he and a few teammates snuck out of their training camp to go partying in Paris.

"I am getting more starts, but I am not an automatic first choice pick. I have to work every day because Robinho is better than me and I must always earn my place," the 18-year-old told the Corriere della Sera newspaper.

"In France the mentality is different to in Italy, as here you need more professional behaviour. I am asked to focus only on football and to be more careful in every aspect of my life."
