The midfielder completed his transfer to Roma yesterday.
"I have an excellent rapport with all of my teammates and never had a row with any of them," he told Viola Channel.
"I don't understand why this story was in the papers that I had an argument with Mario Gomez. I care about everyone.
"I always had a great relationship with the fans and want to thank them for our years together. Many things happened and I said several times I wanted to remain in Florence, but we were unable to reach an agreement on the contract.
"Another option emerged that was positive for both Fiorentina and me, so everyone is happy. It's a shame to leave Florence and I will always cheer on the team, because I like the city and its people. I thank everyone."
