Fiorentina chief Sandro Mencucci says they're determined to build on last season.
The Viola finished fourth in the table and reached the Coppa Italia final.
"This year Fiorentina have done great things despite the many injuries we had during the course of the season.
"The club doesn't just want to keep hold of this good group, it also wants to look to improve it.
"With the recovery of our best players and with a bit of luck, I am convinced that next season we can reward ourselves with great happiness.
"More than anything, I really hope I can see Giuseppe Rossi and Mario Gomez play together. Given the injuries they have had, they really have been unfortunate.
"I am very pleased for the two young attackers Babacar and Bernardeschi. Soon we will see them in Serie A and I hope one of the two of them can stay at Fiorentina next season."
