The Italy striker hit a wonderful hat trick inside the last 25 minutes to complete a stunning comeback for Vincenzo Montella's men.
The win moved Fiorentina up to fifth in Serie A while Juve remains third, and Rossi insists the result shows the Florence outfit can compete with anybody.
"We are all happy for what happened this afternoon," he told Sky Sport Italia. "We are built to win. There are great elements in this team and we showed today that we can compete with any team.”
Despite his contribution, Rossi emphasized the spirit of the team as the reason for the turnaround.
“They were three very nice goals, but in the second half the team played incredible," he said. "The team showed great courage and great heart to win. At halftime Montella said we had to give more and we did that.”
Rossi also intimated that he hoped that his own performance had enhanced his chances of starting regularly for Italy.
“I hope Prandelli is happy with my performance,” he said.
