"It made me sad to hear him say those things," Heinze told Radio Marca.
"I do not know if it is true or not, but it is certainly a shame that someone with the experience of Ferguson is capable of saying such stupid things.
"If it was a fan or another player then maybe I could understand it, but someone with his experience doing that is not normal.
"Ferguson is someone that has earned respect both on and off the pitch and for him to say such daft things really is disappointing.
"But the facts speak for themselves. He wanted me to go and now says that he wanted me to stay? I was there for three years and gave everything.
"I really could not care less what other people say. I value what my team-mates say here far more."
