Debt has to be assessed as a % of shareholder paid up capital and/or a % of trunover.
10 million debt for a club with 2 million capital is worse than 100 million for a club with 50 million capital etc.. so usual Uefa general comments that need to be more thoroughly explained before they can be understood. Probably smaller clubs who 'just' make it into CL or Uefa Cup will be hit worst!
