It was Min9 when Mallenco correctly ignored to call a penalty for Trabzonspor. Burak was down in the box, but I think the tackle by CSKA defender wasnt that much to let him down. I also agreed not to show him a YC for dive-in. But, in the last minutes of first half, CSKA goal keeper hold the ball with his hands after it has been deliberately kicked to him by his team-mate. Mallenco hasnt whistled anything. That was an obvious indirect free-kick in the box. For the rest of foul detection, he was around the standarts.
He used the method to warn first without showing any yellow. After implementing the technique for two positions, he decided to let his cards out of his pocket. I really dont think, referees should directly apply this anology. Because, players start to focus on the lack of consistency in decisions in these circumstances. Most of cards for rest were correct. He again correctly send Doumbia off by 2nd YC.
