A section of Celtic supporters have publicly voiced their opposition to the potential appointment of Robbie Keane as the club's next manager, displaying an X-rated banner outside Celtic Park as speculation surrounding the managerial position continues to intensify.
The banner, which appeared near the stadium and was later shared on social media by supporter group Bhoys Celtic, contained a blunt message aimed at both Keane and influential shareholder Dermot Desmond.
It represents the clearest sign yet that parts of the Celtic fanbase are unhappy with reports linking the former Republic of Ireland striker to the vacancy.
Keane is understood to have held constructive discussions with Desmond and is reportedly among the leading candidates should Celtic decide to appoint a new manager ahead of the 2026-27 campaign.
Why are some Celtic fans opposed to Robbie Keane?
While Keane enjoyed an outstanding playing career and has built managerial experience in recent years, his candidacy has divided opinion among supporters.
Much of the criticism centres on his decision to take charge of Israeli club Maccabi Tel Aviv in October 2023 amid the ongoing conflict in Gaza. The appointment attracted criticism from some sections of the football community at the time, particularly in Ireland.
Keane responded to those concerns by insisting he was focused solely on football and did not wish to become involved in political matters, stating that he had accepted the role as a football manager rather than a political figure.
Nevertheless, some Celtic supporters have continued to express reservations about his association with the club, and those concerns appear to have resurfaced as reports linking him with the Celtic job have gathered momentum.
The controversy comes despite Keane's recent managerial success at Ferencvaros, where he added further silverware to his coaching CV before departing at the end of the 2025-26 season.
What is happening with Celtic's managerial search?
The situation remains fluid, with Celtic still expected to hold discussions with current boss Martin O'Neill regarding his future. O'Neill guided the club to a Scottish Premiership and Scottish Cup double during a dramatic campaign and remains a popular figure among supporters.
However, club officials are understood to be exploring alternative options should O'Neill decide not to continue for another season.
Reports suggest Keane has already begun considering a potential backroom team. Former Celtic captain Scott Brown, current Celtic B coach Johnny Hayes and coach Stephen Glass have all been linked with possible roles should Keane be appointed.
Their existing connections with both Keane and Celtic are viewed as strengths, but the reaction from supporters demonstrates that any appointment would not be universally welcomed.
FGG says: Celtic face a delicate balancing act
Managerial appointments are rarely judged solely on coaching credentials, and the reaction to Keane's candidacy highlights that reality. While his recent achievements suggest he has earned consideration, football clubs must also understand the mood of their supporters.
A banner from one supporter group does not necessarily reflect the views of the entire fanbase, but it does indicate that resistance exists. If Celtic do decide Keane is the right man for the job, the club may need to work hard to win over a significant section of supporters from day one.
