The 28-year old Italian midfielder has made the permanent shift from the Reds to La Viola after arriving on Merseyside three years ago and says he is looking forward to beginning a new chapter back in his homeland.
"I had no doubts about Fiorentina because they wanted me and the project here is very interesting," he said.
"Now the most important thing is that I will never return there and I want to concentrate on my new cycle.
"There's nothing wrong with my condition, I trained well with Liverpool and did the same as my teammates.
"However the club decided to sell me. I had a great experience in England and if I went back in time I'd do it all again."
