Celtic head into the 2025/26 campaign as overwhelming favourites to defend their Scottish Premiership crown. After claiming yet another league title last season, bookmakers have placed them at incredibly short odds, suggesting an almost certain repeat. Their dominance at home has been so consistent that many betting markets view the real battle as who will finish second, with Rangers the only side even remotely close in the odds. Hearts and Aberdeen are priced far further back, with the rest of the league considered outsiders.

 

In Europe, however, the picture is very different. While the top European betting sites offer competitive odds and bonuses, fans of “The Bhoys” already had their hopes dashed last week, as they were knocked out in qualifying by Kazakhstan’s Kairat Almaty. The trip to Central Asia proved just as difficult as many had warned, and their defeat means they now drop into the Europa League. Even there, they will struggle to be considered among the favourites. When it comes to outright Champions League betting, the spotlight remains firmly on Europe’s elite clubs, with Celtic barely mentioned as contenders. The contrast between domestic certainty and continental doubt is striking.

Summer Transfers and Squad Changes

Celtic’s summer window was busy but also somewhat divisive among supporters. The biggest headline was the emotional return of Kieran Tierney on a free transfer, bringing leadership and top-level experience to the backline. Other arrivals included Benjamin Nygren and Shin Yamada, adding options in wide and attacking areas, while promising defender Hayato Inamura joined from Japan. Several youth players and loanees were also brought in, aimed at bolstering depth and future development.

 

On the flip side, the club cashed in on Nicolas Kuhn, who departed for a significant fee, and sold centre-back Gustaf Lagerbielke to Braga. A number of fringe players left on loan, thinning out the squad in certain areas. Fans have voiced concerns that the reinforcements may not match the quality of those departing, particularly with European competition in mind. While the net business has been pragmatic, there remains a sense that Celtic might be one or two signings short of being fully prepared for the demands ahead.

Managerial and Tactical Outlook

Brendan Rodgers remains firmly at the helm and has made it clear he intends to see out his contract. His philosophy has not changed much: a possession-based approach built on a 4-3-3 system, with inverted full-backs stepping into midfield and a focus on controlling games through pressing and tempo. In tougher matches, Celtic often adjust into a 4-4-2 defensive block, with Kyogo leading the press alongside a midfielder such as Reo Hatate.

 

Tactically, the team is well-drilled, but injuries have already posed challenges. Right-back Alistair Johnston faces a lengthy spell out after suffering a hamstring injury, leaving Anthony Ralston and younger options to fill in. Aside from that, the squad is relatively healthy, with captain Callum McGregor, Kyogo, and Matt O’Riley expected to carry much of the creative and attacking responsibility. The addition of Tierney gives Rodgers both defensive stability and attacking width, a key ingredient in breaking down stubborn domestic opponents.

Domestic and European Rivals

At home, Rangers are the only genuine threat. With new investment and fresh faces, they are pushing to close the gap, but bookmakers still see Celtic as heavy favourites. Hearts, buoyed by outside investment, are the most likely of the rest to mount a challenge, but they remain far behind in both squad quality and depth. Aberdeen, Hibs, and others will target top-six finishes and cup runs rather than a genuine title tilt.

 

In Europe, the scale of the challenge is enormous. Celtic’s budget and resources pale in comparison to the giants of England, Spain, Germany, and Italy. Even if they had reached the group stage, they would have been seeded low and paired against some of the continent’s strongest sides. Progress to the knockout rounds would have represented a major overachievement, but in recent years, even securing a respectable points tally in the groups has been difficult. Realistically, Celtic’s best hope of a deep run now lies in the Europa League, where the competition is still fierce but more balanced.

Outlook

Domestically, Celtic look set for another title. The odds, the squad, and recent form all point toward them extending their dominance in Scotland, with Rangers left chasing. In Europe, however, the situation is less forgiving. The gulf in resources and quality remains a major obstacle, and much will depend on how they respond in the Europa League. Beating the odds in 2025/26 will not mean winning the Premiership – that seems almost expected – but proving they can compete credibly on the European stage. For now, at least, the bookmakers believe Celtic’s glory will remain at home.
