Roma striker Pablo Osvaldo has described himself as "a lunatic".

The 26-year-old Argentina-born Italy international claims that he wants to become an adolescent again.

"I always want to change and think happiness must be elsewhere," he told La Repubblica. "This is the first time I've had two consecutive seasons in one club.

"There are days when I feel sad and would like to be a different person, to lose myself in the world. I miss Argentina and my childhood. I'd like to be an adolescent again.

"I am a bit of a lunatic. One day I feel strong, the other useless. I fight, I score, I react, but I do everything to excess. I was forced to grow up, but there's a part of me that rejects the idea of growing up. I make pointless fouls, but at that moment they seem right."

Osvaldo joined Roma from Espanyol in the summer of 2011.
