The exit of Edu has been expected for months, but the confirmation marks the culmination of a massive period of change at the club.The arrival of Oliver Glasner as head coach in July felt like a line in the sand, the start of another new era at the City Ground.There have been plenty of those in recent times, but the club must now hope this is the start of a period of stability after an extensive period of restructuring.Glasner is the fifth head coach since Edu’s appointment last summer. Since the departure of Nuno Espirito Santo last September, Ange Postecoglou, Sean Dyche and Vitor Pereira have all come and gone.During the Brazilian’s tenure, there has been a significant degree of change well beyond his position and in the manager’s office. The upside now is that there are no longer obvious gaps in key positions.Lina Souloukou, the chief executive officer, stepped down from her role on June 5, after initially being appointed in January last year. Souloukou — who was one of the few remaining high-ranking female executives within football — has subsequently been replaced by another former Olympiacos employee.Theodore Giannikos began work as the new CEO at the start of this month, with the club stating that he would “lead the club’s strategic direction and oversee the delivery of its long-term ambitions”. Giannikos has spent the last decade working at FIFA in several roles, including director of strategic partnerships and media projects, director of legal strategic projects and director of member associations services.He spent nine years at Olympiacos, where he was a vice president and board member. He also served as an executive board member of the European Club Association (ECA) from 2012 to 2016. Additionally, he served as a Court of Arbitration for Sport (CAS) arbitrator and as a member of various UEFA committees.Craig Mulholland left Forest (Photo: Lewis Storey/Getty Images)Craig Mulholland, the head of development and talent management, departed at the end of the season to take on a new role as chief football officer at the Scottish FA. In October, chief football officer Ross Wilson left to take on a similar role at Newcastle United.But both men have now been replaced. Central to that is the respected figure of George Syrianos, who had previously been the global technical director for Forest, Olympiacos and Rio Ave — the three teams within the Evangelos Marinakis football empire.Syrianos now has the title of chief football officer and is the most senior figure on the football staff. Club sources, speaking anonymously to protect relationships, say his influence has grown in the aftermath of those departures. He was promoted into that global role in 2024, after previously impressing as Forest’s head of recruitment, following the club’s promotion to the Premier League in 2022. He is effectively a replacement for Wilson, rather than Edu.
