Celtic are heading into a summer that is not just a rebuild, it is one of the biggest overhauls the club has faced in years. The scale of change is clear and it shows the squad has not been built to last.
The numbers are difficult to ignore. The Celtic squad and recent transfer activity already shows a team that was ill-prepared for this season.
Loan deals, short-term additions and players moving in and out have left a squad that looks full on paper but is nowhere near settled.
Once it’s broken down, the size of the rebuild becomes obvious. Celtic are not tweaking the squad, they are facing a turnover that runs deep and a major task is facing whoever the next manager will be.
Pick one player to sell for ‘£20m’ this summer. Engels or Nygren?
Who you picking and why, Celtic fans…
Celtic facing massive squad rebuild across multiple areas
The scale of change is not limited to one position or one group. It runs through the entire Celtic squad.
- Loan returns: Joel Mvuka, Junior Adamu, Julian Araujo, Tomas Cvancara, Benjamin Arthur, Marcelo Saracchi
- Out of contract or short-term: Kelechi Iheanacho, Alex Oxlade-Chamberlain, Kasper Schmeichel
- Players still to prove long-term value: Michel-Ange Balikwisha, Paulo Bernardo, Sebastian Tounekti
- Key players attracting attention: Arne Engels, Daizen Maeda, Reo Hatate, Auston Trusty, Hyunjun Yang and Benjamin Nygren
That is a significant portion of the squad already in flux. When that many players are uncertain, it is not a controlled rebuild.
It becomes a reset that forces multiple decisions at once, rather than gradual improvement over time.
Celtic risk losing control of rebuild scale
The concern is not just how many players leave. It is whether the club can replace them properly in one window.
Callum McGregor has already pointed to the wider issue when he wants to remain at Celtic for the rest of his career, but on the condition they match his ambitions.
That condition carries weight. It highlights that even within the squad, there are questions about direction and progression.
If too many players leave at once, recruitment becomes reactive. That increases the risk of more short-term fixes instead of long-term solutions.
Celtic are not just replacing players. They are trying to rebuild large parts of the squad at the same time.
That level of change does not guarantee improvement. It creates pressure to get every decision right in one window.
This is a massive rebuild. The real challenge is whether the club can control it, or if they can even deliver for the next Celtic boss.
