Ronald Koeman does not agree with Gerard Pique's claim that referees favour Real Madrid over other LaLiga sides.
Pique this week quoted a former referee who, according to the Barcelona defender, said 85 per cent of officials in Spain's top flight were from Madrid.
In an interview with Post United, Pique said: "How are they not going to whistle in favour of Real Madrid? Even unconsciously, how are they not going to give more for one side than the other?"
Pique added last season, when Madrid won the title, was "the most absurd refereeing experience ever".
En route to the championship in 2019-20, Zinedine Zidane's side earned a joint-high 11 penalties and conceded a joint-low two.
But Koeman disagrees with his centre-back, who reportedly could be sanctioned for his comments, insisting the league's referees are honest.
"Those are [Pique's] words. I can only comment on this year, not on previous seasons," Koeman told reporters.
"There are decisions in which we have had no luck, but I don't think they are against us. They are decisions of the referee and also VAR.
"I always think that the attitudes of the referees are honest. They give what they see and are not in favour of any team."
The numbers have changed this term as Madrid have received a joint-low 37 cards (36 yellow, one red) but only Cadiz (none) and Huesca (one) have won fewer than their two penalties.
The defending champions have also conceded a joint-high seven spot-kicks heading into this weekend.
Barca have been shown 38 cards, won five penalties and given away two.
Koeman was speaking ahead of Sunday's trip to Real Betis, which follows hot on the heels of Barca playing 120 minutes against Granada in the Copa del Rey on Wednesday.
Victory after extra time in that match set up a double-header with Sevilla in the semi-finals, adding to an already packed schedule.
Koeman feels the calendar is "killing the players" and pleaded for help from competition organisers.
"It is difficult," he said. "The number of games that the big teams have, with three competitions, on top of the COVID situation, makes everything more difficult.
"You have to talk with the players to see how they are physically, their feelings. Sometimes you have to give someone a rest to be able to have everyone in the best condition.
"If we count tomorrow's game and Wednesday's, there are 12 games in a row, of which 11 are away from home. And that's playing at 21:00, coming home at 03:00 in the morning. It is difficult for the players to be able to play all the time. We need help.
"I hope that one day UEFA or LaLiga will think about the number of games and what this does to the players. It is not normal. The games we've had to play, the trips, the schedules, playing the Supercopa between four teams, in my opinion, is a lot.
"Each coach has his opinion about the fixture schedule that the players have to go through. I think this has to stop, it's killing the players. We will have many injuries as a result of this. It is impossible.
"Hopefully one day they will make a decision to help the players with their fitness."
