AC Milan striker Ronaldo says he wants to play his way into a new contract.

"I'm going to try and impress this year to win the trust of the club," Ronaldo told Sky Sport Italia. "I want to earn things for myself and at the moment I haven't deserved an extension.

"If I manage to impress then I don't see there being problems in negotiations with the club at the end of the season, but I need to get stuck in as I don't want anything gifted to me."
