I did a few doodles, you can play:
1 A vs B 2 C vs D 3 E vs F 4 G vs H
Then winner of 1 vs winner of 2, winner of 3 vs winner of 4 and losers of the same games play each other.
Then you'll get a league table with 2 teams with 2 wins, 4 with 1 win and 1 loss and 2 teams with 2 losses. Goal difference can be used to help and do a seeding. This is assuming golden goal so no draws.
