|Univ. San Martin||-||River Plate|
A referee has to be as neutral as possible, and also consistent, if he wants to do a good job. Buitrago was not neutral, because he made a big mistake when he conceded a non-existent penalty to San Martín. Later, one or two similar situations in the other side, didn´t meant the same decision by the referee.
Buitrago influenced the result, by giving San Martín the chance to score after a Peruvian player fell down inside River area. That wasn´t a penalty, in fact - in my opinion - wasn´t even a doubtful action. But with that goal, San Martín won the match.Later, Falcao was pushed inside the area... it was also doubtful, but this one was a bigger penalty than the other. The Colombian just said "go on!".
SM was a bit better during the 1st half and River was definitely better during the 2nd, but could not tie. Buitrago used 8 cards, often OK, often because of childish things. He seemed to have refereed the 2nd half knowing that he had made a mistake with that penalty, because he looked serious but he wasn´t really in control.
