The Fiorentina striker currently leads the scoring charts in Serie A with 12 goals and is looking forward to representing his country in Brazil, where they will face England, Uruguay and Costa Rica in the group stage.
"I see the World Cup as a dream come true, the kind I've had since I was a child," he told Il Corriere dello Sport.
"The dark period of injury is behind me now and I don't think about it anymore. I just want to play at 100 per cent hoping to be at my best for the World Cup too.
"I am confident, as we have a great squad and are all really good friends. The partnership with Mario Balotelli works on and off the field too, as we talk a lot, joke around and have the same taste in hip hop music."
Rossi joined Fiorentina from Villarreal in January.
