Ronaldinho says he's feeling better about his career at AC Milan thanks to the influence of coach Leonardo.

Milan are still seven points behind League leaders Inter, but some pundits still feel they can offer a credible title challenge.

"It's tough, very difficult. But if I am happy then things go much easier," Ronaldinho told Rai 2. "It's easy to work with Leonardo because he knows how I like to train and how I like to play."

Ronaldinho also refused to deny reports earlier this season that Milan patron Silvio Berlusconi told him to swear to give nothing but his best in front of his team-mates.

He said: "I never speak about what happens in the dressing room."
