In this case, it would be necessary to resort to the result of the direct clashes between those teams that finish the tournament in equality of points. To tenor of this system of tiebreaker, the Real Madrid would finish carrying the title in almost all the combinations. Barcelona and Seville are those that worse have it in this system of tiebreaker.
Real Madrid
Independently of what occur in his clash of this Sunday in Valdebebas, against the Seville, the led by Zidane would be champions if it gave a cuádruple tie in the leadership. The whites have him won the "goal average" (difference of goals) above the Barcelona and Athletic, and against the Seville have the advantage to having won in the duel of the gone to the ones of Lopetegui, in the Sánchez Pizjuán 0-1.
If it gives the stage of a triple tie between the Real Madrid, the Barça and the Athletic, the title would go for Santiago Bernabéu. The final result would be the same if the scored tie gave between Madrid, Barça and Seville, because the merengues already would add 9 points in these particular duels with Barcelona and sevillistas. And the whites also would heave with the title if it produced a triple tie with Athletic and Seville. That is to say, that any triple tie in which it was immersed the Madrid, would do him champion.
Athletic of Madrid
The Athletic, by his part, has him won by "goal average" to Barcelona and Seville, so it would be champion in the case of any tie with these two teams, so much triple like double, but no with the Real Madrid.
Barcelona
After the tie of this Saturday in front of the Athletic, the ones of Koeman lost an opportunity of gold the Barcelona only has him won the "goal average" to the Seville, so only a tie in the leadership with the hispalenses would give them the title, but achieves to finish leader in solitary.
Seville
Of all the teams, the Seville is the one who less options has in these moments, although it still has to confront to the Madrid. Has the ones to lose in all the combinations, but if it wins in Valdebebas by two or more goals, would win him the "goal average" particular to the Madrid and then could be champion in a hypothetical scored tie with the whites.
