Real Madrid boss Jose Mourinho has again attacked the Liga's fixtures.
Mourinho is convinced Barcelona have been favoured in the draw.
"We are in a situation where as soon as we drop a point we lose the championship, although not mathematically so," said the Portuguese. "I am not stupid and I know this.
"There is a team that played in the Champions League on Tuesday and have no game in the league until the following Sunday [Barca this week], while another one is forced to play in Europe on Wednesday and then Saturday in the league [Madrid next week].
"Not everyone has the same chance to compete. Not everyone plays under the same rules. The competition is not open. I will not comment further."
