Barzagli's agent Claudio Orlandini insists that Fiorentina were at fault for the breakdown in negotiations with Barzagli.
"Only a Florentine native like Andrea would have offered to accept half the offer that Wolfsburg made in order to wear the Gigliati shirt.
"He sent a clear message, but Fiorentina didn't respond to that. Obviously I respect the club's point of view and I wish them all the best.
"The difference between what we were asking and what they offered was minimal - it amounted to £100,000.
"Andrea was willing to give up a lot of money to play for Fiorentina, but they didn't take our requests into consideration."
