Former Real boss Camacho takes his Osasuna to Madrid this weekend.
He said: "There is not a clear point of reference. I've talked a lot about Mourinho, but I do not know what he is going to give to Madrid. I seriously hope he makes a good team - he has a lot of personality as a coach.
"Playing against Madrid will always be difficult, but we will always try to win this match from the very start."
