Real Madrid assistant coach Aitor Karanka insists Kaka's latest setback is not an old injury.

Kaka is out of their clash with Valencia due to a muscular injury.

"Kaka hasn't recovered yet," admitted Karanka.

"I've suffered muscle injuries myself and I can tell you they are tough to determine; it sometimes seems you're fit to play when you really aren't. He isn't suffering from his previous injury; he's simply recovering from this muscle strain."
