Markarian slams referee after Uruguay loss
Loustau oversaw Peru's 2-1 defeat in Lima in the South American qualification section on Friday, awarding a controversial penalty for a foul on Luis Suarez before sending off defender Yoshimar Yotun in unclear circumstances shortly after for a foul on the Liverpool striker.
And although Makarian admitted his player had acted stupidly, he feels Argentine official Loustau's decision to reduce his side to 10 men before half-time was soft.
"I'll do my best to make this World Cup referee not go because I'm not ashamed to say it was totally decisive," said the 68-year-old.
"What Yotun did was silly but I've seen worse, like elbows or double uncollected simulations that go unpunished."
Peru are now five points behind Uruguay, who occupy the fifth-place play-off position in the CONMEBOL qualifying pool.
