At the beginning of the match, Buitrago had to stop it because there was no light in one area of the stadium.
Buitrago gave a penalty to Libertad. It looked like it was a penalty, but you could discuss about it. It was a difficult call, to me it was not a penalty, but it was impossible for Buitrago to see that there was no contact. It was a very difficult call.
Buitrago did not want to show his red card to a player of Libertad. He could have shown it, but he gave the player a second chance.
Buitrago had to show his red card to a player of San Luis. The player had already seen the yellow card. He made a foul, Buitrago told him to calm down. 5 minutes later he made an other foul, Buitrago had to show him the second yellow card and the red card.
Libertad got a very good result in Mexico. Now San Luis has to get those points out of his home if they want to get the knock-out stage.
