The former AC Milan striker declared: "How much have the three years at Milan changed me? Lots, but that is only normal.
"It was the second stage of my career. The first part was the debut, but then I had to progress for the level I had reached in the provinces. At Milan I suffered and slaved away, but I learned a lot. And now I am ready to start the third phase of my career in Florence and it will be the most important part.
Despite Gila's frustration at Milan last term he remained professional and didn't react angrily to being brought on as a 89th-minute substitute against Genoa on January 27.
"It was tough and I asked why he needed to make the substitution," Gila recalled. "But if the Coach tells me to go out there then I do it.
"The team comes first and I wasn't angry with Carlo Ancelotti or anyone else. But five games in a row on the bench did make me think about my future in Milan."
