Celtic’s 2025/26 campaign ended in a domestic double, with the Premiership and Scottish Cup secured and Benjamin Nygren finishing as top scorer with 21 goals. The club now faces a pivotal summer, with the permanent managerial vacancy shaping every decision as it heads into a Champions League qualifying cycle.
The Candidate Field
Martin O’Neill has returned as interim manager for the second time this season, having initially stepped in after Brendan Rodgers resigned in October 2025 and again following Wilfried Nancy’s departure on 5 January 2026 after less than a month in post. At 74, O’Neill is priced at evens to retain the role permanently but is not widely considered a long-term solution by the board.
Robbie Keane is the current betting favourite at 4/5, with Sky Sports reporting constructive talks and a relationship with majority shareholder Dermot Desmond cited as a significant factor.
Keane won league titles with Maccabi Tel Aviv and Ferencvaros, though both came in leagues with limited European depth. His appointment would represent a tactical unknown at Champions League level, where Celtic must navigate two qualifying rounds before the league phase.
This uncertainty has left the support completely split, and the rumour mill is working in absolute overdrive. Because of the massive number of punters who bet on football here in the UK, the bookmakers are incredibly sensitive to any whispers coming out of Parkhead. A sudden plunge in the odds for someone like Robbie Keane usually means genuine money is talking, giving us a decent clue about the board’s next move long before an official announcement.
Craig Bellamy, whose Wales side were eliminated by Bosnia in the World Cup play-off semi-final, is now available in principle having previously remained committed to the international campaign. Bellamy’s club management experience remains limited, though his tactical profile leans toward high-intensity pressing systems. Roberto Martinez has also been considered by the board according to Sky Sports, bringing European experience from his time with Belgium and Portugal.
Squad Continuity
The identity of the incoming manager will determine how Celtic approach contract renewals and recruitment. Nygren’s 21-goal season makes him a retention priority, but his future likely depends on whether the new head coach intends to build around a direct attacking structure or shift to a possession-based system.
A manager with a defined style, whether Martinez’s structured build-up or a higher defensive line under Bellamy, will require different profiles across the squad.
Champions League Implications
Celtic’s qualifying path for 2026/27 begins in July, leaving minimal time for a new manager to implement a system before competitive football resumes. Keane’s record in European knockout rounds with club sides is limited. At the same time, Martinez oversaw Belgium to a World Cup semi-final and managed Porto, offering more relevant experience at that level.
The board’s decision on timing, whether an appointment comes before or after the summer transfer window opens, will significantly influence squad planning.
The double secured in 2025/26 provides a stable base. Who builds on it remains unresolved.
