Celtic have gone for continuity in the chief executive's office by appointing interim incumbent Michael Nicholson on a permanent basis. Nicholson became the club's third chief executive of 2021 on September 10 after Dominic McKay departed suddenly following just 10 weeks in the role. Nicholson has been in an acting role ever since and has been planning for the January transfer window with manager Ange Postecoglou and recruitment staff. The 45-year-old has been with Celtic since 2013, initially arriving as company secretary and head of legal, before being promoted to the role of director of legal and football affairs two years ago.
