Heinze continues:
"There was a quick chat when I signed and Mr Ferguson congratulated me.
"But we haven't discussed anything further.
"We still haven't spoken about whether I'll play centre half or full back.
"I have always said that so long as a manager puts his faith in a player he will be able to play in different positions.
"This is an exciting challenge for me. I'm coming to Manchester because I had an offer from one of the best clubs in the world.
"I'm coming to Manchester with a lot of desire, a lot of dreams and I'll work very hard."
