Heinze insists he should be allowed to join Liverpool and said last night: "This weekend I will travel back to England and, like a professional, I will go to work in Manchester on Monday. I have asked for a meeting with manager Sir Alex Ferguson on Monday about my future. I'm sure that this meeting will tell me what my future is.
"I'm totally convinced that if this offer had been made by another club then Manchester United would have considered it. The rivalry between these two clubs is enormous and now I am at the centre of it."
Heinze's name was jeered by some supporters during the club's 3-2 defeat to Inter Milan in a friendly at Old Trafford on Wednesday but the player himself is not concerned.
Heinze added: "I always was a serious and professional player and during this summer I have not changed."
