AC Milan vice-president Adriano Galliani is confident Kaka will be fit for their Champions League clash with Arsenal.
"Kaka certainly is out of Lazio, we hope to have him against Arsenal. Even Andrea Pirlo should recover fully for Arsenal.
"I hope Kaka and all the players like him are better protected, especially by fouls from behind. This type of foul should be punished with dismissal because it is a foul of a coward, which can hurt, put an end to a career, cause trouble."
