Real madrid are paying silly money for ronaldo?

why are real madrid paying so much money for him i love real madrid always will but he is not worth that much kaka aswel but i was more happy when kaka signed for madrid but we need spainish players and good defenders cuz that was the main reason we have been losing my main signing would be aspecially david villa gael clichy and i would rather have ribery more than ronaldo,raul albiol i would get rid of van der vaart,rvn,drenthe,guti,raul,metzelderand keep huntelaar,robben,snieder, hala madrid
