I don't know, I think you would make the Play Off round in the qualifiers, obviously would then depend on who you got as some of those ties can become very tricky. Fortunately, you're endeavors have give you some protection with the coefficient.
That said, I am not sure Celtic would do much with the new dollar rolling in. I am actually a Englishman who likes to see the Scottish League producing in Europe. However, I have been really critical of Celtic for the past decade and particularly in the last five years.
The reason I say this, is that if they hadn't become so provincial in their outlook and just focusing on lording over your lot/the rest of Scotland when you went into liquidation, there isn't any real reason why they shouldn't have been in the sort of Benfica/Ajax/Porto category of teams. I mean, yeah, Scotland doesn't have the greatest board casting rights, but the fans and income, if they qualify for the CL, puts them up there.
Now essentially, they're back, after stinking in Europe for years, off the back of your success in Europe dragging Scotland's coefficient up after they tanked it. I just do not get the mentality, especially as with you gone they virtually had no competition for years so really should've have focused on Europe.
