After 12 minutes of the match, Cristiano Ronaldo stepped into the area and faced Ronald Araújo. He fell in the area and a few seconds later the whistle of the referee was heard.
The referee awarded a penalty and the VAR did not argue with him. The centre-back put his arm between his chest and neck, but gave the impression that there was no aggression to warrant the penalty.
Amidst protests and complaints from Barca, Cristiano took responsibility and addressed the fateful point. After the 'o.k.' of the technology, Ter Stegen was on the line to try to neutralize the '7' in one of its specialties.
But CR7 managed to put the 0-1 on the scoreboard with a shot to the right of centre. The German goalie was beaten and the iconic "Siii" ended up rumbling in an empty Camp Nou.
It is the 19th goal Cristiano has scored against Barcelona in his career, of which, counting the latter, he has celebrated 13 in the Camp Nou.
