Heinze is hoping to be given the green light to join Liverpool when a Premier League arbitration panel meets to discuss his case today.
He told the Mirror: "I am a professional and I am concentrating every day on my career with Manchester United, but now my head is thinking about Monday's meeting and I want a definitive solution.
"My lawyers are optimistic about this case.
"My idea has not changed and my objective is to go to Liverpool. I will always be grateful to United, but now I hope they allow me to get my wish."
