Khizanishvili's United career went pear shaped when he was red carded against Doncaster Rovers back in October when first arriving on-loan.
Now back with Rovers, he told the Evening Chronicle: "If they make a decision and I go back in January, I would be happy to play for Newcastle again.
"I spent three months there, and I was very happy.
"I spoke to Chris (Hughton), and he's a very honest guy - he tells you what he thinks face to face. That's what you need as a player.
"He's a respectable man, and I really enjoyed the games I played."
