The La Liga refereeing controversies of the 2019 season have been a subject of intense interest and debate among fans, analysts, and media outlets alike. These disputes have taken place during matches between the two leagues, with some incidents involving the use of controversial tactics or decisions by referees.

One of the most notable instances was the decision made by the referee in the second leg of the Real Madrid vs Barcelona match on January 28th. The match ended 2-2 after extra time, but the referee decided to award a penalty kick to Barcelona for fouling Real Madrid defender Luka Modric. However, this decision was met with widespread criticism from fans, commentators, and even football experts who argued that it was unfair and potentially illegal. Some felt that the referee had not given enough credit to Real Madrid's defense, which ultimately led to Real Madrid winning the match.

Another controversy occurred when Real Madrid's captain, Sergio Ramos, received a yellow card after being sent off in the second half of a crucial match against Valencia. Ramos complained about the ruling and refused to leave the pitch, leading to a heated exchange with his manager, Zinedine Zidane. Zidane accused Ramos of "foul play" and threatened to take disciplinary action against him. Ramos then walked out of the stadium, leaving the match void of any clear-cut winner or loser. This incident has been widely criticized as an example of poor communication between officials and players, and has raised questions about how referees can make decisions without proper guidance.

In addition to these cases, there have also been other controversies involving the use of controversial tactics or decisions by referees. For example, the match between Real Madrid and FC Barcelona in the Copa del Rey final in May 2019 saw referee Jose Luis Martinez award a goal to Barcelona for a foul committed by Real Madrid defender Alvaro Morata. However, this decision was later overturned by a higher court due to a technicality, resulting in another controversy.

Overall, the La Liga refereeing controversies of the 2019 season have been both entertaining and thought-provoking, highlighting the complex nature of the sport and the importance of fair and transparent decision-making. While some may argue that such controversies are necessary to ensure fair play and prevent abuse of power, others see them as a necessary part of the game and argue that they help to maintain consistency and fairness throughout the season. Ultimately, the success or failure of these controversies will depend on how effectively they are addressed and how they are handled by the governing body and league organizations.
