Real Madrid cannot afford to keep dropping points in LaLiga if they want to stay in contention in their title defence after failing to win their last three games, manager Carlo Ancelotti said on Saturday.

Real Madrid cannot accept that the competition continues to be governed by a discredited refereeing system, whose main people responsible, far from being removed, continue to play a decisive role in decision-making.

Carlo Ancelotti said the LaLiga title race has "reached a point where you can't slip up" as Real Madrid, Barcelona and Atlético Madrid go into this weekend's games with just a point between them at the top of the table.
