Real Madrid's accounts are subject to this Sunday's Barcelona v Villarreal match. Everything depends on what Setién's team do against them.
For Madrid, who are seven points above Barcelona, to win the league this week, Barcelona would only have to pick up one point from their next two matches.
Thus, a Barca win against Villarreal or Espanyol would eliminate the option of Zidane's men celebrating the championship against Alavés on Friday.
For them to win it three days later, i.e. Monday 13th July, Barca could only win one of the matches against Villarreal and Espanyol. If that happens, Real Marid will be champions if they beat Alavés on Friday and Granada on Monday.
