When the player took the dive and Kovalenko awarded a penalty, every defending player close to him went CRAZY because it was quite obvious that the attacker took a huge dive, but I think from where Kovalenko was, it looked like there was contact. We can blame his angle but we also have to blame him.
The assistants did a good job during this match. No influence on the match and no wrong offsides either.
The difference between Irmatov who in my opinion is one of the best referees in the world, and other Uzbeki referees is miles.
