Atletico Madrid midfielder Koke was fuming after defeat at Barcelona.
The result was secured after Diego Costa was shown a red card for abusing match officials.
Koke was not afraid to intimate that Atletico have received rather harsh from officials when playing at the Camp Nou, however.
"Whenever we come here [to the Camp Nou], something happens," Koke said after the game.
"In the last 11 games, I think there have been seven red cards and not all of them have been fair."
Given that their title bid is effectively over, Koke is keen to ensure that Atletico hold onto second spot in LaLiga Santander.
"We must try to stay as high as possible in LaLiga," he noted.
"We will have to watch what happened [against Barcelona].
"What we talk about stays inside the dressing room and no one has to know [what is said]."
