The 2021/2022 season saw a significant shift in refereeing standards in La Liga, with several critical decisions made by referees that have had a profound impact on the quality of play and the integrity of the game.

One of the most notable incidents was the controversial decision by referee Mateo Borrero to award a penalty to FC Barcelona for a foul on Real Madrid's Cristiano Ronaldo during a crucial match in the 2021-2022 season. The decision was widely criticized as it appeared to favor Real Madrid at the expense of their star player, which led to a prolonged legal battle between the two clubs.

Another critical decision came when referee Juan Carlos Oñate gave a controversial call during a match against Valencia in the 2021/2022 season. The referee ruled that a goal was valid after the ball had gone out of play but then overturned the decision when the ball landed inside the box. This decision caused further controversy and resulted in a lengthy legal dispute over whether the referee should have been suspended or not.

Other incidents included the controversial decision by referee Jose Manuel Paredes to rule that a header from Luis Suarez was a foul, despite no physical contact being shown, which led to the striker receiving a red card. Similarly, referee Javier Sotomayor awarded a penalty to Real Madrid's Diego Costa for a foul on Lionel Messi during a crucial match in the 2021/2022 season, which ultimately led to the Argentine international receiving a red card.

Overall, these decisions highlight the importance of clear and consistent refereeing standards in La Liga, particularly when it comes to key moments such as penalties, goals, and fouls. Without good refereeing, games can become frustratingly long and difficult to follow, leading to lower attendance figures and potential disciplinary issues for both players and officials. By implementing better refereeing practices and maintaining high standards, La Liga can ensure that its matches are both entertaining and fair, ensuring that every match is played to the highest standard.
