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.
Real Betis faces a team that managed to get the La Liga trophy, everyone will say Real Madrid is stronger than Real Betis, the fact is like that. In this match, Real Madrid is not as strong as imagined, it is certain that Ancelotti will field a second layer team. There is no reason for Real Madrid installs the main squad, because the Champions League Final is more important than Real Betis.
