The 25-year-old was shipped out on loan to Rio Ave after penning a new contract.
It is his seventh loan spell since joining the Blues eight years ago and the Brazilian wants the cycle to end.
"I'm tired of playing here and there, I need a place where I can feel at home. I want to know that in July I will return to the same place, to the same house.
"I'd have a good season on loan, but I'd come back and was soon loaned again. There was no point in going out on loan, playing well, coming back, not being used and being loaned again.
"There comes a time in your career that makes no sense anymore. By the way, I said exactly that three years ago and it didn't go so well at Chelsea, it generated some discomfort."
