Vinicius Junior felt Gabriel Jesus’ equaliser for Manchester City against Real Madrid should not have stood.
Madrid were stunned in the last-16 first leg at Santiago Bernabeu on Wednesday as Kevin De Bruyne’s 83rd-minute penalty earned City a come-from-behind win.
Gabriel Jesus cancelled out Isco’s opener, although Madrid complained about a push from the City forward on Sergio Ramos, who was later sent off for a foul on the Brazilian.
Vinicius lamented the decision not to penalise Jesus for a foul on Ramos for the equaliser.
“The whole stadium saw Gabriel Jesus push Ramos. He did the same as me with [Riyad] Mahrez in the first half,” he said.
“They give us bad calls. We are the team with the most Champions Leagues and it will always be that way.
“It has been a very clear foul and I don’t understand why he hasn’t called it.”
Madrid had appeared in control courtesy of Isco’s opener on the hour-mark, only to collapse late.
But Vinicius remains confident in his side’s ability to turn the tie around in Manchester on March 17.
“We’ve got to keep cool, we’re going to win there and pull off the comeback,” he said.
“We lacked focus in that final 15-minute period and that’s why they got the two goals. We have to improve.
“We know that the return leg will be tough, but we’ll pull off the comeback.”
Blancos boss Zinedine Zidane also refused to throw in the towel afterwards, despite his side having a European mountain to climb at the Etihad Stadium.
Zidane said: “We had a good game for 75 minutes.
“We’re annoyed by the defeat, but the tie lasts 180 minutes.
“Now we have to take the positives. There aren’t many positive things in the result, but we had a good game apart from the last few minutes.
“We were good for 70 minutes. Now we have to go there and win if we want to go through.
“We needed 10 more minutes of concentration in a very difficult match and, in the end, we paid for it.”
