Jesse Marsch is being linked with Celtic.
The Hoops are set to move for a new manager as Ange Postecoglou departs for Tottenham.
American Marsch has been a free agent since his sacking by Leeds in February.
He held talks with Southampton, Everton and Leicester City, but ultimately chose to sit out the season.
Sky Sports says Marsch is now on Celtic's shortlist and is set to be invited to interview for the job.
