It all happened about 10 minutes into the first half when Merlos took an alleged foul by González Pirez on Jonathan Herrera inside the area and awarded a penalty to Riestra. The complaints of all of River, which was up 3-0 on the scoreboard, were felt and the referee was called to review the action.
After watching the action on the monitor at the side of the playing field, everything seemed to indicate that the judge would annul the penalty, however, when he returned to the field he was surprised and decided to show the red card to González Pirez.
Riestra was preparing to execute the maximum penalty when Merlos was called again. This time, when reviewing the VAR, it was clear that there was an advanced position of the local soccer player who had brushed the ball to Herrera. Upon verifying this, all further action was invalidated.
In this way, Merlos ended up taking a free kick in favor of River and put an end to the great controversy of the afternoon.
