Gazza has battled alcoholism, drug and mental health problems, but there is no longer anything the family can do to help.
In a television interview for a documentary to be shown in the new year, he says: "He's probably going to die soon. I don't think there's any point helping him. We're wasting our time.
"If I could wish, I would wish that he would go away from us.
"Everyone thinks he's Gazza but because he's the top player doesn't mean he's a good dad or a good person to be with, does it, really?"
'Surviving Gazza' will be shown on Channel 4 on Monday January 5.
