Cassano struck the winner in victory over Napoli.
"Of course I think about the World Cup and I'd like to take part," he told Sky Sport Italia.
"I am going to Brazil, though I don't know if on vacation or with the Azzurri. Let's leave controversy aside, as I am playing well with Parma and I'm happy here.
"It was a perfect evening, because the team played a great game. I am happy with the victory, as other times we didn't get the points despite deserving to.
"I am convinced that if the team works hard, then everyone is crucial. I scored a goal and did well, but the team has to help me. I am the icing on a perfect cake."
