He has made no secret of his desire to move to United's bitter rivals Liverpool in what has been one of the summer's longest transfer sagas. But Big Sam would like nothing more than to bring him to St James' Park.
However, the player admits he has been left in the dark over some of the ongoing negotiations.
The Argentine insists a clause exists in his Old Trafford contract which allows him to leave United if another club makes a bid of £6.8million.
Liverpool are believed to have met the asking price, but United are unwilling to allow the deal and Heinze is reportedly thought to be considering legal action. And Newcastle are said to have offered £200,000 more than Liverpool.
Heinze, though, is optimistic he will soon secure a move away from the Premier League champions, but perhaps we are fooling ourselves that he will be heading to Tyneside.
Heinze: "Sometimes the player is the last one to find out where he will play.I know there are several teams interested in me and that makes me feel really proud.
"I'll know precisely in what team I'm going to play at the end of the week. In a few days we'll see what will happen."
