Bilbao is surely better team here, but i must play under on this margin.
They are without Mumbru and Bertans, two very important players for attack.
Also, Bilbao always play games on little number of points.. defense is in first plan.
Home team also play good defense, especilay home. They recievec from one Barcelona 57 points.
I expect one defense game and not see Bilbao over 70 points.
This margin is good and worth to try with under.
