Barcelona ace Luis Suarez was furious after being sent off in their Copa del Rey success against Atletico Madrid.
Suarez scored in last night's second-leg, which finished 1-1, before seeing red.
"Expulsion? Here we know how everything goes," snapped the striker, who wants Barca to appeal the red card as it will mean he misses the final.
"It was not even a foul, I just turned around and it looked like they just saw what they wanted to see.
"What the club can do now is appeal."
Suarez added: "I laugh at the dismissal. These are things that have no explanation, but we are already accustomed to it."
