Jose Mourinho has stressed that Kaka still has a role to play at Real Madrid, and added that the attacking midfielder will get the chance to prove his worth at some point this season.The Brazil international was continually linked with a return to AC Milan throughout the summer, but the move did not materialise because of financial reasons."Neither Kaka nor anyone else is a dead weight," Mourinho stated at a press conference."Against Granada we went in another direction, [Karim] Benzema, [Jose] Callejon, and [Luka] Modric played and we also wanted to give some rest to those who played against Barca."The three who were left out were the first choices, but there will be a time when Kaka will be an option once more."The 30-year-old midfielder has yet to feature in an official game for Madrid this term.
