So, as you know, UEFA is changing how competitions work next season. They'll be abandoning the Group Stage and adopting a League table. With 3 games played this season, we can have an idea of how this League table will look like next season since no team as played each other more than once and most of these clashes would also be possible under the new format.
To my knowledge, no tiebreakers for this new League system have been announced, so I simply ordered the clubs by Points > Goal Difference > Goals Scored. If all teams were tied in these 3 points, I used the club coefficient table (was only needs for Sporting, Sparta Praha and Sturm Graz). I avoid H2H because I'd need to come up with more tiebreakers, like Disciplinary Points (red and yellow cards).
Also, there's only 32 teams playing this season, so the 4 last spots are open to imagination. Top 8 go through, the other 16 go to a play-off system for the Round of 16.

I wonder what’s next, shape of the ball?
