Sources: Celtic Lay Groundwork for 'Massive Overhaul', Update on Summer Manager Appointment

Celtic Football Club is preparing for a massive overhaul ahead of the summer, following a turbulent 2025-26 season marked by managerial instability and poor results. Sources indicate the club has laid the groundwork for sweeping changes, including a new permanent manager appointment by summer 2026.[1][2][3]

The saga began with Brendan Rodgers' second departure from Parkhead in October 2025. Celtic quickly appointed Wilfried Nancy, the 48-year-old Frenchman from MLS side Columbus Crew, on a two-and-a-half-year deal. Nancy, MLS Coach of the Year in 2024, was seen as a stylistic successor to Ange Postecoglou, with his attacking wing-backs and player development praised. Recommended by head of football operations Paul Tisdale, Nancy's debut included key fixtures against Hearts, Roma in the Europa League, and the League Cup final versus St Mirren.[1]

However, Nancy's tenure lasted just 33 days. He was sacked after losing six of eight games, including the League Cup final to St Mirren and an Old Firm derby defeat to Rangers. This dismal run contributed to Celtic suffering six Premiership losses—their most since 2012-13.[2]

Interim boss Martin O'Neill returned for the second time this season, confirmed on January 5, 2026, until the campaign's end. O'Neill, who won seven of eight prior games and three league titles (2000-01, 2001-02, 2003-04), expressed honor at the role and wished Nancy well, emphasizing unity to return to winning ways.[2][3]

With the club eyeing a summer reset, insiders reveal groundwork for a 'massive overhaul' in squad and staff. The board prioritizes a proven European tactician for the permanent role, amid pressure to reclaim dominance after defensive frailties exposed this term. Fans anticipate bold recruitment to rebuild momentum.[1][2]
