The squad will be paid bonuses in groups of four matches. To pocket the extra money they have to win three and draw one.
The season is divided up into ten blocks of four with the last two matches to be negotiated separately.
On gaining promotion, a fixed sum will be shared out amongst the players. Last year it was set at Pts500m ($2.7m/B3m).
Spanish soccer club Atletico Madrid is changing its bonus system in the race for promotion.
