The referee and his assistants did well during the entire time of the match and kept things under control.
Mozaffari Zadeh likes to let the match flow and doesn't stop it for every collision and fall which is good because this way the match has a chance of having a good pace.
Last season, this referee only officiated two Champions League matches while guys like Minoru Tojo and Al-Hilali got more matches with is bad for the competition.
