The Barcelona goalkeeper was shown a red card for protesting after his side's 2-1 loss at Real Madrid, furious at the official's decision not to award a late penalty to Adriano
Valdes was furious at the official's decision not to award a late penalty to his side following a challenge from Sergio Ramos on Adriano and protested angrily after the final whistle.
Although further from the action than any other player on the pitch, Valdes protested more vehemently than any of his teammates and had to be restrained by a member of the club's staff.
Shouting angrily in the referee's face, Valdes was shown a yellow card but continued to protest until Perez Lasa produced a red moments later.
According to the referee's report, Valdes verbally insulted the official, shouting: "You [the officials] s**t yourselves [by not awarding a penalty against Madrid at the Bernabeu], you have no shame."
And Perez Lasa claimed the 'keeper, who will leave Barcelona when his contract expires in 2014, kept on repeating: "You have no shame."
The referee's full report reads as follows: "Once the game was over and while were still on the field of play, I booked Barcelona player, No. 1, Victor Valdes Arribas, for squaring up to me with his arms aloft and his voice shouting, recriminating one of my decisions. I then sent off the same player for shouting repeatedly in my face, from just a few centimetres: 'You [the officials] s**t yourselves, you have no shame.'
"After he was sent off, the same player persisted with his attitude and kept on saying, in the same tone: 'You have no shame.' He had to be restrained by his teammates and a delegate from his club. Once we were in the tunnel, the same player persisted with his attitude and repeated the same thing as he had before, still shouting: 'You have no shame, you have no shame.'"
Meanwhile, Gerard Pique stoked the flames after the game by saying: "I hope Perez Lasa apologizes next time he referees one of our games."
Real defender Ramos was handed by a five-game ban by Spain's football federation (RFEF) for insulting referee Miguel Angel Ayza Gamez in a match against Celta Vigo in January and Valdes could now face a similar sanction.
