even though sevilla later losing against bilbao and Betis can win big against Madrid later, so that it makes both points equal to 67 but still sevilla will still qualify for the champions league next season because this season sevilla won head to head from Betis.
Looks like it's going to be upside down

Real Betis lost and Sevilla winon big against Athletic Club.
The two teams face different clubs, yes Real Betis will be a little heavier with Real Madrid. While sevilla is a little lighter because is an Athletic Club not from the top lalagia.
