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.
