Celtic's summer transfer business has faced scrutiny over the last three seasons, with the board accused of not investing enough in the first team.
The team sold players like Kyogo, Adam Idah, and Nicolas Kuhn, and failed to re-invest, leading to an early Champions League exit.
However, when money is spent properly, success follows, as seen in Celtic's Champions League performance and league and cup double last season.
Celtic spent close to £30m in the summer of 2024, and according to the CIES Football Observatory's report, here is how the squad's value looks now.
The CIES Football Observatory has released its weekly report on clubs whose squad values have increased since the end of the 2024 summer transfer window.
In summary: Celtic's squad value has changed significantly since the 2024 summer transfer window.
