Real Madrid coach Jose Mourinho has revealed that Kaka is still not 100 per cent fit and will miss their Champions League Group D encounter against Dinamo Zagreb at the Bernabeu on Tuesday.The former AC Milan man is still shaking off a leg injury he sustained last month against Real Sociedad and is just one of a long list of players missing from the squad.Ricardo Carvalho, Angel Di Maria, Marcelo and Alvaro Arbeloa will all be absent from the Zagreb clash as well."I cannot say my formation, but the players who have spoken in the press conferences this week will be starting," Mourinho told reporters."Kaka still has a little problem, but he has overcome the injury. We do not want him to return to the pitch unless he is 100 per cent."As for Sergio Ramos, I do not know if he will play on the flank, it all depends. He is playing brilliantly in a centre-back role."Mourinho went on to praise Lassana Diarra who will get the nod against the Croatian side."Lass is a starter and he can do everything, play in the middle, on the wings or as an offensive midfielder. He has character and he will play tomorrow," Mourinho said."We are top of the group with 12 points from four wins and we want to stay in first place. We want to play well tomorrow [Tuesday] and entertain the fans."Kick-off at the Bernabeu is at 20.45CET. Madrid have already beat Dinamo Zagreb 1-0 this season on the first matchday.
