The appointment for this match was originally given to Mohsen Torky who is another Iranian elite referee but the Syrians argued and it got changed. 5-1? I guess it's not always the referee guys.
Al-Sadd's fifth goal barely passed the line and the referee's assistant got it absolutely right. Another good call by the officials.
One sided and the result shows that. In my opinion, it should have been 10 not 5.
