At 1:30 when the player shoots the ref, you can here someone in the crowd shouting : SAH SAH
It means : correct, in this context it meant "you're correct, go on"

lol Zak :) They applauding to him too :) but why he knocked out that player which defend him? lolol

Lol how is the referee crazy? He was being molested by a bunch of players, and he fought back...!
