Pato has clashed on-field with teammates and struggled to recapture his best form since returning from injury.
But in Paris with Brazil for the friendly against France tonight, Pato says: "Playing as a first striker is something I like, and I think I'll do well in this role, but I'll do what the coach asks me, for the national team and for Milan.
"Playing behind the striker for Brazil? I have a coach who believes in me, and even (Milan coach Massimiliano) Allegri believes in me, so it depends on how we play.
"I am happy, I'm always happy , I just have to train and feel comfortable."
