Zinedine Zidane has swotted away claims by Gerard Pique that Real Madrid benefit from favourable decisions by referees and insists nothing has changed in the title race despite Barcelona's slip-up at Sevilla.
Victory would see Madrid leapfrog Barca at the top courtesy of their superior head-to-head record.
Speaking after their draw, Barca defender Pique told Movistar Plus that it would be "very difficult" for them to retain the La Liga title, expressing his belief that "It's going to be difficult for Madrid to lose points" having seen what has happened in the games since the restart following the coronavirus-enforced hiatus.
Zidane, though, showed little interest in Pique's remarks at his pre-match media conference on Saturday, telling reporters: "Nothing has changed.
"We have a game tomorrow and we have talked about 11 finals. We will give everything and without thinking about anything else."
Asked about Pique's comments, he replied: "Say one thing or another. What interests me is tomorrow's game.
"I have my opinion, but I will not comment on it because it can happen the other way around. The truth is that what encourages us is tomorrow's game. Nothing else.
"I don't believe they are favouring us," Zidane said when pressed on whether refereeing decisions had been benefiting Los Blancos.
Real Sociedad are contending for the Champions League places but have been held by Osasuna and beaten by Deportivo Alaves in their two games since the restart. They sit sixth going into Sunday's game, level on points with fifth-placed Getafe and two points behind Atletico Madrid in fourth.
"I don't know if they are playing worse, the results have been worse, but they can get you into trouble at any time," added Zidane. "Tomorrow is another final."
