Roberto Mancini says he's left the Italy job due to the lack of support from FIGC President Gabriele Gravina.

Mancini resigned as Italy coach on Sunday amid claims of an agreement to take the Saudi Arabia national team post.

But he told La Repubblica: "I explained to him (Gravina) that in these months I needed to be given support and calm, but he didn't do that and so I resigned.

“Should I have done it earlier? Perhaps. But I left the Nazionale with 25 days to go before the next game, not three days.

“Gravina had been trying for a year to revolutionise my staff. I tried to tell him that at most he could add a couple of new faces, but he couldn't take away two members of a group that works and had won. If anything, it should be me who decides to substitute a member of my staff.

“Gravina had for a while thought about things very differently from me. I was massacred purely for my decision. I wanted to send a signal to the President, he could've helped me if he had wanted to.

“I had only asked that so that I'd have some peace and quiet over the next few months. Obviously, I would've gone if things didn't go well and we failed to qualify."
