He was good in the technique but he made much mistakes in the discipline. The match was not easy to control, but he was not good, the cards were ok, but Paraguay deserved at least 4 more under the criterion of the referee. For me the red card could have been avoided,
The players of Colombia asked for a penalty. In my opinion it was not, but the player did not wanted to confuse the referee, that was a mistake for Martinez because he showed the yellow card for the second time to the player, a shame.
Colombia did not deserved to win by 2 goals, Paraguay did not know what to do with a men more all the second half, Colombia did what they had to, keep trying to score and win, and now are 2nd in the group with 4 points behind Brazil who has 6. Chile has only one point and the other teams (Venezuela and Paraguay) with only one game have no points.
