The Brazilian international has been struggling with a injury in his left foot since the 1-1 draw with Reggina on February 7.
“As soon as I manage to deal with the pain, I will get back to playing,” Kaka revealed.
“In the past I played for a year with pain in my knee, but last week’s pain was different.
“Anyone who thinks that I don’t want to get back to playing is out of their mind.
“Sadly it seems that this an injury that doesn’t happen often and it keeps getting inflamed.”
