Vinicius Jr saw Allan Nyom sent off for Getafe after being on the pitch for 37 seconds. Kylian Mbappe struck the only goal of the game on 80 minutes - three minutes after Nyom's red card. Alexis Sancris was then sent off on 84 minutes.
"He wouldn't speak to us or check the VAR; it's strange he doesn't even look at it," said an angry Adrián Liso as he left the stadium.
Kiko Femenía also expressed his disappointment: "He booked me in an absurd way and it affected my game. Nyom's should have been a yellow, not a red. All the decisions went in their favor. The referees remain firm in their convictions."
After the match, the players' comments conveyed a widespread sense of frustration.
"We were playing a great game, but the refereeing decisions destroyed our work," said an unnamed Getafe player.
Meanwhile, Sancris stated: "It wasn't a red card, but that's how it went. Vinicius was playing his game, it was my mistake to come on."
