1. Origins and Foundation: The Birth of a Footballing Institution
Celtic Football Club was founded in 1887 in Glasgow, Scotland, by Irish Catholic immigrants led by Brother Walfrid of the Marist Brothers. Their purpose was not only sporting but deeply social: to raise funds and support for the impoverished Irish community in Glasgow’s East End. From its very formation, Celtic embodied a sense of identity, integration, and community — a club rooted in heritage but open to all who shared its ethos.
The team played its first match in 1888, quickly becoming a competitive force in Scottish football. Its iconic green and white hoops, unmistakable crest, and passionate fan base soon became symbols not just of sport, but of culture and identity.
2. Early Success and Establishment
Celtic’s breakthrough achievements pre-World War II laid a foundation that would persist for decades. They won multiple trophies in the Scottish League Division One and built rivalries, most notably with Rangers F.C., forming one of the most intense and historic derbies in world football — the Old Firm.
This rivalry transcends sport. It has layered historical, cultural, religious, and political dimensions — framed largely by Celtic’s Irish Catholic roots versus Rangers’ historical association with Protestant unionism. That context gives every Old Firm fixture an intensity rarely seen elsewhere in world football.
3. The Golden Era: Jock Stein and the Lisbon Lions
The 1960s were transformational for Celtic. Under manager Jock Stein, the club reached unprecedented heights. The pinnacle came in 1967, when Celtic won the European Cup — becoming the first British team ever to do so. This team, forever immortalised as the Lisbon Lions, completed a treble of Scottish League title, League Cup, and European Cup in a single season.
The feat was remarkable not only because of the trophies, but also because the entire squad was composed of players born within 30 miles of Glasgow — a unique achievement in European football history.
4. Domestic Dominance: Trophies and Records
Celtic is among the most decorated clubs in world football. As of the end of the 2024–25 season, Celtic had won:
- 55 Scottish Premiership titles
- 42 Scottish Cup trophies
- 22 League Cups
- 1 European Cup (1967)
The 2024–25 title was particularly significant: it was their 13th league title in 14 seasons and brought the club’s total major honours to 120 — surpassing Rangers for the most in Scottish football history.
This era of sustained excellence underlined Celtic’s dominance in Scottish football. Their numbers aren’t simply statistics — they represent generations of success, cultural pride, and supporters’ lifelong devotion.
5. The Modern Era: Managers and Tactical Evolution
Brendan Rodgers (Return and Impact)
Before 2025, Brendan Rodgers had already stamped his authority on Celtic with multiple titles. During the 2024–25 season, his team scored 112 goals and conceded just 26 in the league, showcasing a blend of attacking flair and defensive solidity.
Rodgers’ approach combined modern tactical flexibility with Celtic’s traditional attacking ethos. Under him, the club continued prioritising domestic dominance while seeking greater success in European competitions.
A Turbulent 2025–26: Managerial Instability
The 2025–26 season did not begin as smoothly. After Rodgers resigned in October 2025, veteran manager Martin O’Neill returned as interim boss and immediately had a positive impact, going unbeaten domestically and elevating Celtic to the top of the Scottish Premiership table.
Under O’Neill’s short spell, Celtic reached the League Cup final and achieved their first Europa League away win in the Netherlands in over two decades — against Feyenoord.
However, in December 2025, Celtic appointed Wilfried Nancy as manager on a two-and-a-half-year contract. The decision backfired: after just 33 days, including heavy defeats (e.g., 3–0 to Roma in the Europa League and losses domestically), Nancy was dismissed. His tenure became the shortest in Celtic’s history — and statistically, one of the worst based on win percentage.
Following Nancy’s departure in January 2026, Martin O’Neill returned again — this time until the end of the 2025–26 season — bringing experience, steady leadership, and renewed focus on European competition and league success.
This period highlighted underlying instability and challenges within the club’s sporting leadership, a theme with significant implications for Celtic’s ambitions both domestically and in Europe.
6. Celtic’s Squad and Key Personalities
Veteran Leaders and Icons
One of Celtic’s most enduring figures is James Forrest, the Scottish winger whose commitment spans more than a decade. In 2025, Forrest became Celtic’s most decorated player ever, surpassing Bobby Lennox with 26 major honours. He also scored goals in 16 consecutive seasons, a testament to his longevity and influence.
Goalkeeping Stability: Kasper Schmeichel
In 2024, Celtic brought in Kasper Schmeichel, the Danish captain and former Premier League winner with Leicester City. Schmeichel quickly became a leader at the back, delivering a run of clean sheets that matched a record not seen in Scottish football since 1906. His performance was central to Celtic’s defensive strength and title triumphs.
Emerging Stars and Key Contributors
Beyond the veterans, Celtic’s modern squad blends youth, flair, and tactical dynamism. Players such as Nicolas Kühn have become central figures — Kühn’s statistics in 2025 showed him as one of Celtic’s top performers, with double-digit goals and assists across competitions.
Other contributors have included homegrown talents and exciting additions from European leagues — reflecting Celtic’s strategy of combining academy development with shrewd recruitment.
7. Transfer Activity & Market Strategy (2025–26)
Celtic’s approach to transfers in 2025–26 was a mix of loans and targeted signings that reflected both strategic caution and ambition — though some fans and commentators viewed it as underwhelming.
By January 2026, confirmed moves included incoming loans such as Julian Araujo and Tomáš Cvancara — aimed at addressing defensive and attacking needs.
Beyond confirmed deals, Celtic pursued further reinforcements. Reports in early 2026 linked the club with targets like French winger Fares Ghedjemis and Hungarian winger Damir Redzic — illustrating a desire to boost attacking options. However, negotiations for Ghedjemis stalled due to fee disagreements, showing the challenges smaller clubs can face when engaging in the transfer market.
This cautious yet focused market activity highlighted the fine balance Celtic must maintain: competing domestically and in Europe while managing financial sustainability — a challenge familiar to clubs outside football’s wealthiest leagues.
8. Domestic Competitions: League and Cup Campaigns (2025–26)
Scottish Premiership Battle
In the 2025–26 Scottish Premiership, Celtic faced a much tighter title race than in previous years. Their historic dominance was challenged not only by Rangers but also by Heart of Midlothian (Hearts) — with Hearts even leading at certain points, intensifying the title race.
An example of the competitive nature of this season was Celtic’s 1–3 home defeat to Rangers in January 2026, a result that underscored the challenge of maintaining consistency and momentum.
Managerial turnover and squad adjustments added wrinkles to Celtic’s campaign, but with O’Neill back at the helm, the club aimed to steady its course and preserve its prospects for another league title. This struggle reflected the broader evolution of Scottish football — where Celtic’s previously near-unassailable dominance now encounters real, structural competition.
Domestic Cups
Celtic’s 2024–25 ended in bittersweet fashion in domestic cup competitions: while they secured both the league and League Cup, they narrowly lost the 2025 Scottish Cup Final to Aberdeen in a penalty shootout — a rare setback in knockout competition.
This intricate balance of triumph and heartbreak underscores football’s unpredictability — especially in cup competitions where single days define legacies. Celtic’s fans, while focused on trophies, understand that such moments are integral to the club’s narrative.
9. European Competition: Legacy and Recent Performances
While Celtic’s domestic record is remarkable, their European ambitions have seen periods of both glory and challenge. The high watermark remains the 1967 European Cup, a pinnacle few clubs outside Europe’s top five leagues have achieved.
In recent seasons, Celtic’s performances in European competitions have been more mixed. The 2024–25 Champions League campaign saw them reach the play-off round, signalling progress and competitiveness at higher levels.
The 2025–26 season saw early setbacks — including elimination by Kairat in the Champions League qualifying round. Celtic’s involvement then pivoted to the UEFA Europa League, illustrating the challenge of navigating modern European football where slim margins and small differences define success.
Under O’Neill’s stewardship in late 2025, Celtic achieved a significant away victory in the Europa League — the first in over twenty years in the Netherlands — hinting at untapped potential and tactical fortitude.
The European landscape remains a key focus for Celtic: not only for sporting prestige but also for revenue, global visibility, and player development.
10. Financial Performance & Infrastructure Development
Off the pitch, Celtic’s financial health has been robust. In the fiscal year ending June 2025, the club reported record revenue and profit growth, driven by strong domestic performances, European competition revenues, and commercial activity.
Revenue for the period reached over £143 million, while profits more than doubled year-on-year. Significant player investment (£42.6m) reflected ambitious competitive aspirations.
Simultaneously, Celtic invested in training facilities and academy infrastructure at Lennoxtown and Barrowfield, enhancing pathways for youth development — crucial to long-term sustainability and talent cultivation.
These developments ensure Celtic doesn’t merely compete as a historical giant, but is structurally positioned for future growth.
11. Women’s Team and Broader Sporting Ecosystem
Celtic’s identity isn’t confined to men’s football. The Celtic FC Women’s team has grown in prominence, both competitively and institutionally. In 2025, season tickets for the women’s team went on sale, indicating stronger supporter engagement and growing importance within the club’s sporting framework.
In late 2025, Celtic FC Women appointed Grant Scott as manager, signalling ambition in the Scottish Women’s Premier League and reinforcing the club’s commitment to women’s football excellence.
This expansion enriches Celtic’s identity: now, success isn’t just measured on one pitch, but across a broader footballing platform that engages multiple communities and drives inclusivity.
12. Club Culture, Fans, and Identity
Celtic’s supporters are among the most passionate and widespread in world football. From Glasgow to Dublin, across Europe, Asia, and the Americas, Celtic’s fan base is known for its unwavering loyalty, vibrant matchday atmosphere, and deep cultural attachment to the club’s values.
The anthem “You’ll Never Walk Alone” resonates at Celtic Park — a stadium known affectionately as Paradise — and encapsulates a collective spirit that defines the club: unity, resilience, and pride. This emotional and cultural bond between the club and its supporters transcends mere fandom — it is a living tradition passed from generation to generation.
13. Looking Forward: Challenges and Aspirations
As Celtic moves through 2026 and beyond, several key strands will define its journey:
A. Domestic Competition
The Scottish Premiership is more competitive than in years past. With Rangers revitalised and Hearts mounting sustained title challenges, Celtic’s path to silverware demands consistency, strategic leadership, and tactical refinement.
B. European Ambitions
Celtic’s quest for deep runs in European competition is ongoing. While historic success remains unmatched outside the elite leagues, translating domestic dominance into European impact requires squad depth, tactical adaptability, and consistent investment.
C. Leadership and Stability
Managerial changes in 2025–26 underscored the importance of stability and long-term planning. Ensuring continuity — whether with O’Neill or beyond — will be crucial to maintaining momentum.
D. Youth and Development
Investment in academy infrastructure positions Celtic to nurture future stars. Bridging the gap between academy prospects and first-team impact could define competitive sustainability in years to come.
E. Cultural Strength
Above all, Celtic’s identity – its heritage, community, and global fan base remains its greatest asset. Coupled with modern ambitions, this culture ensures Celtic’s story continues to evolve in compelling, unforeseeable ways.
