Soccer tournament 384 teams

Take a look at the attached. It handles the scheduling of the 5 matchdays and computes all of the point totals. All you would need to do is input the goals for/against for each match. I did the first two groups to demonstrate. It is all based on ROW(), so do not insert rows. You should be able to insert columns if you please, though, perhaps to add goal differential. It isn't as versatile as you requested, but it should fit your specifications. You can adjust the number of teams by increasing/decreasing the number of rows, but it's designed for groups of 6. I hope it helps!
