AC Milan director Adriano Galliani has revealed that Kaka's injury worries are not as bad as reported.

"Kaka has a sportsman's hernia (groin/pelvic injury) and you can't tell when that will heal," Galliani told journalists.

"The thing is that you just don't know how long is needed for the recovery. He could even be back in action on Sunday.

"All we need is a little optimism and not to exaggerate," he concluded
