The 24-year-old’s current contract with the Black Cats is set to expire at the end of the season.
“In any contract talks, a change of management will stall things because the new manager needs to see who he wants,” Colback told the Sunderland Echo.
“And, with the position we are in in the league, it’s not really at the forefront of anyone’s mind.
“I have been approached [to restart talks] but I said I would just be patient and see how it went.
“But I’m hoping to get something sorted.”
