The arbitration controversies most remembered by Barcelona in El Clásico

The Barça and the Real Madrid star year after year the most thrilling party and expected by the fans of the balompié Spanish. No only inside Spain, but also to international level. In fact, 'The Classical' no only shows the greatness of the two teams, but also the importance of the referee's management to handle a commitment of such envergadura. Now that the 'case Negreira' keeps on everyone's lips, there are several moments from beginnings of century in which the Barcelona group has felt prejudiced by the referees.

The first occurred in a Classical suspender belt where Losantos Omar was protagonist of a bad memory for the culés. With the party equalised, Rivaldo attained to beat the goal merengue during the aggregated time and like this give him a triumph agónico that allowed them compete by the title. However, the referee cancelled the so much for understanding that the spherical rebounded in a footballer of the Barça giving step to the offside, although the true is that the ball struck in the white defender Iván Helguera.

A year afterwards would be Muñiz Fernández the one who would prejudice to the Barcelona in Santiago Bernabéu. Although the club did not go through his more successful stage, still was competitive in this type of stages in front of the eternal rival. The Catalans kept the tie (1-1) although the referee cancelled a legal goal of Gaizka Mendieta and did not sentence a penalti on Luis Enrique that would have comported to the second yellow for Fernando Iron.

Five seasons afterwards went in in scene Undiano Mallenco, one of the referees with greater prestige in the Spanish football. It is remembered for expelling precisely to Oleguer Preys but not applying the same criterion with Lass Diarra in the Classical in which Leo Messi marked his first 'hat trick' on the lawn of the Camp Nou. Added to this, left to happen a clear penalti of the same French player on Ronaldinho, a decision that could cost a League for the Barça because the 'goal average' finished giving the title to the Madrid.

Undiano Mallenco Splits two. The 'referee' had one of his worst performances when directing the final of the Glass of the King in 2011 between merengues and Barcelona. The ones of José Mourinho topped champions by an authentic golazo of Cristiano Ronaldo but remained for the memory the big feeling of inconsistencia when measuring the gravity of the faults. Undiano Cancelled a goal of Pedro by an offside more than questionable and also did case omiso to the red of Arbeloa (for stepping in the floor to David Villa), Pepe and Xabi Alonso (by reckless entrances). Besides, only it showed the red cardboard in the minute 120' to expel to to Ángel Gave María when the party was entirely sentenced.

It goes back to the film Muñiz Fernández, this time with 10 years more than experience. In spite of his big route in LaLiga, neither his referee's body neither the Committee of Competition went in in action when witnessing the aggression of Pepe on Leo Messi out of played. The Argentinian yacía in the flat after a fault and the Portuguese happened to his side stepping his hand apropósito. Although the gestures of pain of the '10' were evident, the referee did not show any card and left to happen the situation.

Pérez Lasa left on the table in 2013 his big esteem by the Real Madrid. During the last Classical of his career, denied to sanction a clear zancadilla inside the area of Sergio Bouquets on Adriano Correa in the aggregated time. The impudence was such that the own Víctor Valdés ran to encararlo, what derived in his expulsion and back sanction by four parties. The meeting would finish it winning the Madrid 2-1 but left for the memory one of the most controversial actions in the history of LaLiga. In fact, Pérez Lasa withdrew when finalising the season and never pitó a penalti against of the whites in the 32 parties that directed them.

Finally who more than Undiano Mallenco. The referee sacked of LaLiga in the 2018/19 and in spite of that his performance did not prejudice to the culés in the final result, resulted little comprehensible that a clear manotazo of Bouquets to Messi have remained impune. The action occurred in the previous minutes to the rest and the VAR already was in full operation. However, the aggression went by and the own Leo decided encarar to the white captain in front of the refusal of Undiano to act in this regard.
