And it appears as though the Blues have won the race to bring in the 21-year-old, who looks set to sign a new long-term contract at Wolves before heading off for a season on loan at Birmingham.
Blues head coach Lee Bowyer confirmed that there had been an agreement between all parties and, subject to a medical, Sanderson will be off to St Andrews.
“We are hoping that will get done soon,” Bowyer told BBCWM. “It’s something that I think has been agreed but he is just coming back from an injury so we are just making sure everything is right on the medical side of things.
“I don’t think there’s any problems, it’s just a matter of time, another good addition to the squad.
“He defends properly and when I say properly, he marks, he puts his body on the line and is comfortable on the ball - another one that ticks all the boxes.”
United have made a centre back a priority in the transfer market with Jack O’Connell having undergone a second operation on a knee injury that ket him out for almost all of last season.
Kean Bryan has yet to decide on his future despite being offered a new deal and Phil Jagielka was released at the end of his contract last season.
