Real Madrid were crowned La Liga champions last weekend, but FC Barcelona defender Gerard Pique believes the referees influenced a lot of aspects during the season.
Barca relinquished their league title to their biggest rivals and finished the campaign three points behind the champions.
However, Pique, who is usually outspoken about officiating, also claims the league needs to implement the Video Assistant Referee (VAR).
"The referees have been able to influence things; I'm not going to draw up a list of when we have been favoured or when it's happened to our opponents," Pique was quoted as saying by AS.
"In the end, Madrid won, and we have to turn the page.
"It's still clear that we should implement VAR, which would have been decisive, but there were games where we did not reach our best level. There's no point throwing criticism around. To win the league, you have to be infinitely better.
"With VAR, the refereeing errors will be reduced and therefore we'll all be on equal terms. It will take a lot of the responsibility from the referees on vital decisions, like penalties and goals, and they will make far fewer mistakes.
"I'm not looking for excuses but sometimes it feels as though you are penalised by more than just the score."
