Barca won 2-1 at the Metropolitano, with Eric Garcia seeing red, but lost the Champions League quarterfinal tie 3-2 on aggregate.
Injured Raphinha was with the squad in Madrid and said afterwards: "It was a stolen game, the refereeing was terrible. The decisions they made were unbelievable."
Along those lines, Raphinha also criticised the rough play of Diego Simeone's team: "Atlético committed I don't know how many fouls and didn't receive a single yellow card. I want to believe it's really fear that Barcelona could win."
Atlético goalkeeper Musso responded to Raphinha's criticism , expressing surprise at the Brazilian's statements: "You can't talk about robbery.
"I understand what Raphinha might say, what anyone might say, but let's not portray the tie as a robbery, because it wasn't. We won it on the pitch. We won 2-0 away, and in football, the last man is a red card... I think talking about robbery is crazy."
