City executive chairman Garry Cook has slammed the door on the Brazilian after yesterday's breakdown in negotiations.
Cook sensationally revealed to BBC Radio Five Live: "The agenda we thought we were on was about Kaka coming on a journey with this club but at the end the only journey they were on was a fiscal one.
"We'll continue on our journey but he won't be a part of it. Deals with the greatest players are more than complex.
"It would have been great to have him with us but what got in the way was the behaviour of AC Milan and I think they bottled it.
"We got to talk to Kaka's father. His father said he was very interested in the project and we talked about humanitarian potential factors but when we got into discussions those issues took a back seat and financial demands came to the fore."
