The striker insists Gasperini forced him out of the club following his move to China's Guangzhou Evergrande.
"His choice was more than legitimate and Gilardino had more courage than I did, as I turned down a proposal from China," said Gasperini.
"It was his choice, though, and had nothing to do with me. I stepped aside, observed what was happening and realised he was interested in the negotiation process.
"Therefore, I simply organised for a future without Gilardino."
