Kaka omitted for Osasuna clash
"He (Kaka) trained as normal this week but he's still not ready to return," Pellegrini said at a news conference. "He is over the injury."
Striker Ruud van Nistelrooy and midfielder Guti would hopefully be back in training from Wednesday after injuries, the Chilean added.
Second-placed Real are two points behind leaders Barcelona, who host Villarreal later on Saturday.
