Bernardino Santi said Ronaldo suffers from so many injuries because of the steroids , and anabolic pills he used to take in PSV . The result , his muscular system grew bigger than it was supposed to naturally , and his body wasn't prepared for this. This may be true cause in 1994 there were no anti doping agencies. The doctor said Ronaldo was using it at 17-18 , a very critical age, at the beginning he was more powerfull and stronger but with time the disadvantages started to appear.

I think I'll have to agree with this
