He knows how to keep everything under his eyes and his control. He doesn´t need to intimidate the players with threatening gestures. With Larrionda, they can´t develop the habit of complaining for every referee calls.
He showed how to do it: for slight faults, just whistling. For hard faults, a warning or a yellow card. And for very hard or maliciuos faults, a direct red card (all this seems to be very easy but we know .....). Potosí Galindo kicked Diego Rivero when the ball was very far away, and forced Larrionda to show him the red. Perfect.
The most controversial call was the penalty that Larrionda conceded to San Lorenzo in the 89 minute. Although bolivian players cried out innocence, Bergessio was actually tripped by a Potosí defender.
