However, the Brazilian insists he's not retiring.
He spoke at a Press conference this evening with Majority Owner Flavio Augusto da Silva and CEO Alex Leitao.
“I want to announce that I am not going to renew my contract with Orlando City," Kaka told the gathered media.
“That is all I want to announce. I will honour the Orlando shirt to the end of the season.
He added: “I want to take the opportunity to clarify what I said (to Globoesporte). Pain won't be what is behind my decision. You can ask any football player and they will all have pain.
“My decision not to renew the contract was not based on a physical issue and neither will the next step in my career.
“What's next for me is just this moment, so the only thing I know right now is that I won't be an Orlando City player next season. That is the only certainty I have.
"I feel the need for new challenges."
